Answer: C

1) Default ICA port number?

Citrix Independent Computing Architecture (ICA) protocol is a networking protocol
that runs over TCP/IP using registered port 1494. However, some firewalls are not
preconfigured with details of the ICA protocol. Configuration for the ICA protocol is
straightforward. The ICA protocol is similar to the TELNET protocol. It uses a single
port at the MetaFrame server. The default port is 1494; you can change the port
number using the ICAPORT utility.

2). what is Data Store?

It contains information about
The data store provides a repository of persistent information about the farm that
Each server can reference, including the following:
Farm configuration information
Published application configurations
Server configurations
MetaFrame administrator accounts
Printer configurations
Trust relationships

3) What is Data store?

For each server farm, you need a database called a data store. Citrix Presentation
Server uses the data store to centralize configuration information for a server Farm
in one location. The data store maintains information about the servers,
applications, and administrators in the server farm. Using a data store ensures a
scalable and flexible system for managing your servers.

4) How to check the data store is up or not/

Righhand side value is there it means the connections is through
Next method ?

5) What is LHC (Local Host Cache)


A subset of data store information, the local host cache, exists on each server in the
farm, providing each member server with quick access to data store information.
The local host cache also provides redundancy of the data store information, if for
example, a server in the farm loses connectivity to the data store. When a change is
made to the farms data store, a notification to update the local host cache is sent
to all the servers in the farm. However, it is possible that some servers will miss an
update because of network problems. Member servers periodically query the data
store to determine if changes were made since the servers local host cache was
last updated. If changes were made, the server requests the changed information.

6) What is IMA? Independent Management Architecture (IMA) its a Service

Independent Management Architecture (IMA) provides the framework for server
Communications and is the management foundation for MetaFrame Presentation
Subsystems that define and control the execution of products in a server farm. IMA
manually started or stopped through the operating system Services utility.

7) Purpose of the Data Collector / Zone Data Collectors:Zone data collectors are communication gateways between zones in farms that
have more than one zone. Zone data collectors communicate information used by
MetaFrame Presentation Server to list available applications for users and, when
users open an application, to locate the most appropriate server on which to run the
When resolving a users application request to the least-loaded server in the farm, a
zone data collector queries the other zone data collectors for the information it
needs to identify the server with the lightest load.

8) Configuring Zones and Data Collectors

A zone data collector is a server that manages dynamic information about the
servers in the zone. Each farm has at least one zone.
Zones are designed to enhance the performance of a farm by allowing
Geographically related servers to be grouped together, whether they are connected
to the same network subnet or not.

9) What is Speed Screen?

Citrix has long talked up SpeedScreen Latency Reduction (or SLR for short)
Citrixs SpeedScreen Latency Reduction does two things. Firstly, (and most
importantly), it provides something called local text echo. Local text echo allows

characters to appear on the ICA client devices screen the instant a user pushes the
key on their keyboard.

10) Using a RAID Environment

This section describes factors to consider if you are thinking about putting the
farms data store in a Redundant Array of Independent Disks (RAID) environment.
See the table below for information about cost, performance, and fault tolerance
related to four different RAID configurations.
RAID 0 RAID 0 has no redundancy. It is striped, which means that data is divided
into blocks spanning multiple disks. RAID 0 has multiple actuators (read/write
mechanisms) because of the multiple disk use. More actuators improve read and
write performance.
Citrix does not recommend the use of RAID 0 for critical data, such as a server
farms data store. The savings realized from purchasing fewer disks does not
typically make up for the costs resulting from downtime and support.
RAID 1 RAID 1 uses fully redundant disk mirroring. With disk mirroring, a complete
copy of one drive is maintained on another drive. RAID 1 provides high fault
tolerance and can improve read performance.
However, RAID 1 writes the data twice, which can degrade write performance in
single disk/controller environments. In addition, this type of redundancy requires
twice the disk space.
RAID 5 Like RAID 0, RAID 5 is striped. However, because RAID 5 adds parity to the
data striping, it includes fault tolerance. If one disk in a RAID 5 group fails, the
logical disk continues to function. The parity information is used to recreate data on
a replacement disk. The loss of two disks in a group at one time cannot be
RAID 5 uses multiple disk actuators that provide improved read and write
RAID 10 RAID 10 combines RAID 1 and RAID 0. It is a striped and fully mirrored set
of disks.
It is the best configuration for both redundancy and performance. Because of this, it
is the most expensive storage option.

12. How does Citrix load balancing work?
When a client initiates a connection to the server, a vserver terminates the client


The NetScaler uses a number of algorithms, called load balancing methods, to

method is the Least Connections method.
A typical load balancing deployment consists of the entities described in the
following figure
The entities function as follows:
vserver IP address (VIP) is usually a public IP address. The client sends connection
requests to this IP address. The vserver represents a bank of servers.


server. Identifies the server's IP address, a port, and a protocol. The services
are bound to the vservers.


and then create services by using the server object.

Monitor. An entity that tracks the health of the services. The NetScaler
server does not respond within a specified response timeout, and the
specified number of probes fails, the service is marked DOWN. The NetScaler
then performs load balancing among the remaining services.

8) What's the name of the .CMD file that runs every time a user logs into Citrix.
Whenever a user logs on to MetaFrame, the USRLOGON.CMD file is run. This file is
located in %systemroot%/system32. It is configured to run automatically when each user

logs in.
This file has two functions:
1. USRLOGON.CMD creates the ROOTDRIVE variable. This variable is used by
the Logon Script to identify the user's home directory.
2. USRLOGON.CMD calls USRLOGN2.CMD. USRLOGN2.CMD runs the application
scripts that fix user level problems with certain applications.

CTRL+ALT+DEL hotkey is Ctrl+F1. So if you add that hotkey combo into the
default.ica file in WebInt, it will give users the ability to lock their Citrix sessions by
hitting Ctrl+F1 and walk away from the thin client
4. What is Printer terminology in Citrix

Common Microsoft Windows and Citrix Printing Terms Defined

Citrix Printing Terms
Autoconnected Printers: Printers that are defined for users in their ICA sessions
based off the list of network printers defined on the client machine, but are

connected directly to the print server. During session initialization, the server
attempts to map directly to the print server using the credentials of the user that
initiated the ICA session. If the server is unable to establish a direct connection to
the location, the printer is autocreated in the session instead of being
autoconnected. When a printer is autoconnected, the print job is sent directly from
the server running Presentation Server, bypassing the client device, to the specified
print server outside of the ICA session.
Autocreated Printers: Client local or network printers that appear for the user
within an ICA session and use the ICA protocol to send a print job. Autocreated
printers use the ICA printer naming convention.
Autorestored Printers: A manually created client printer attached to a standard
client printer port. This kind of printer can be created by an administrator or power
user running the Add Printer wizard and manually creating a local printer that is
attached to a standard client printer port. These printers are deleted when logging
off and re-created when logging on.
Autoretained Printers: These are client printers that are added by the user within
an ICA session through the Add Printer wizard by browsing and connecting to
printers enumerated through the client network print provider. When re-creating a
retained printer, all Citrix policies except the autocreation policy are respected. This
means that retained client printers are created exactly as the autocreation policy
would have selected them. Such printers continue to be re-created with every logon
from the same client until the client printer within the session is deleted manually or
the remembered printer connection is removed from the clients properties store.
On a Windows client, the properties store can be found in the user profile under
Client Printers: Any printer available to a user before an ICA session is launched.
Client Local Printer: Printers that are physically connected to client devices
through LPT, COM, or TCP ports.
Client Network Printer: A network printer that appears in the Printers and Faxes
folder of a client device and is managed by a print server. This differs from a print
device attached to a standard TCP/IP port.
Citrix Print Manager Service (cpsvc.exe): Provides printer management for all
ICA sessions including printer policy enforcement, driver installation, client printer
port management, auto-creation of network and client printers, and printer/port
cleanup when logging off.
Citrix Universal Print Driver (UPD): A single driver that is installed and
configured on the server to which an administrator can assign to all client
autocreated printers. This allows for an administrator to not have to manage, install,
and duplicate a potentially large set of third-party print drivers through the server


Citrix Universal Printer: A single generic printer using the Citrix Universal Print
Driver. It is mapped within each session and is not bound to any printer defined on
the client device. It is not enabled by default.
Legacy-style Client Printer Port: The printer ports used by printers created
using the legacy naming convention. Such ports are tied to the client workstation by
The naming convention is as follows:
Where <CLIENTNAME> is the name of the client workstation and <PRINTERNAME>
is the name of the printer on the client.
Standard-style Client Printer Port: The printer ports used by printers created
using the standard naming convention. Such printers are tied to the client
workstation by Terminal Services session ID.
The naming convention is as follows:
Where <ID> is the session ID number of an active session and <PRINTERNAME> is
the name of the printer on the client.
Session Printers: Network printers shared by a print server that are discovered
and attached through a session printing policy.
Unmanaged Printer: Permanent printers attached to legacy client printer ports.
Both the port and printer become permanent fixtures on the server that they are
created on. Whenever the specific client is not connected to the server, the port is
marked offline. However, if a session is opened from the client, the port is marked
online and any queued print jobs begin to print on the specific client printer.
7. How to use datastore for database
8. What is the difference between all citrix versions?
9. What are different load evaluators are available in Citrix

Citrix load evaluators

Many deployments of Citrix where I've had to do health checks have had their
default Citrix load evaluators set for load balancing. The default load evaluator sets
the user load as 100 users per server. This can be very dangerous as this figure has
for all intents and purposes not been tested to and whilst a 100 users per server
may be possible on large powerful servers, it isn't attainable across the board.
Load evaluators on each server need to be configured to just below the stress limit.
So if the servers become unresponsive at a user load of 60 and the server can be

rebooted successfully instead of at 61 users where a reboot does nothing. Then we

can assume that 60 is the stress limit for the server and using n-1 (where n is the
stress limit) would be a fair indicator for the load evaluator.
However we need to factor in transaction times to see whether they are impacted at
n-1 and if they are we need to set the load evaluator for a lower user load.
When loads on servers reach certain points, the associated infrastructure will start
to struggle to meet demands put on it. For example, the network components may
not be able to deal effectively with network requests and as such user sessions may
become unresponsive.
Not knowing your stress limits on resources before going 'live' can become a total
nightmare when a system is 'live' as it may take time to locate the causes and as
I've said before, 'fix it cheaply in test or pay a fortune to fix it later!'.
During one stress testing phase I found above a certain load all the servers in the
farm became unresponsive. The load on the servers was just before the server
stress limits and the aggregate server load on the other associated infrastructure
was therefore very high.
So the first port of call was to check whether the servers could see the rest of the
infrastructure they interfaced with. Which was fine, next I looked at the network and
eventually found out the network card on the data store couldn't cope with the
number of requests made by the Citrix servers.
This is where stress testing shows it's benefits as in most cases non functional
testing is never done on a full scale environment, that is, if the plan is to deploy
1000 Citrix servers for 25,000 users, your test environment won't be the same size
as the cost could be excessive. So the test environment in most cases is a scaled
down version.
The only way to contemplate how thousands of users would affect the system, is to
try to test at the stress limits and monitor the infrastructure components. For
example, using an environment a quarter of the size of the planned primary
environment and using the maximum levels of user load (n-1) per server, it's
possible to get high numbers of test users using the test environment.
By running these stress tests over several days not only would the infrastructure be
able to simulate months of load but also apply consistent levels of stress on
infrastructure components.
This is the stress testing approach I used on a Citrix environment where it was
determined the datastore network cards were unsuitable. Testing using the
expected loads didn't create any infrastructure issues and the Citrix servers coped
extremely well at these loads as the transaction times remained fairly consistent.

When the higher loads were applied, the datastore started to struggle. Fortunately
we were able to change the network cards during testing otherwise the higher loads
would have caused a nightmare if we'd gone into production using these types of
network cards.
It's important to assess the correctness of setup including whether the right
thresholds have been configured for Citrix load evaluators.
Citrix User Policies
With User Policies, you can apply select MetaFrame settings, including shadowing
permission settings, printer autocreation settings, and client device mapping
settings, to specific users or user groups. Using policies, you can tailor your
environment at the user / group level.
Policy rules have three states: Rule Enabled, Rule Disabled, or Rule Not Configured.
By default, not all rules are configured. All unconfigured rules are ignored when
users log on to the MetaFrame server. I highly recommend reducing the amount of
rules set to Rule Not Configured to reduce to need to process the policy and to
speed up the logon time.
Keep with the following when creating a new Citrix Policy:

Decide the purpose for the Citrix policy Why are you creating the policy and who
will it affect. An example of a policy would be to assign them common settings
specific to their function, connection type or geographic location.


Create the policy - You will need to define a name for the policy, assign user(s) /
group(s) to the policy and set the rules that will be the basis of the policy.


Prioritize or rank your policies In order to over come user(s) / groups(s) that are
members of multiple policies you will need to configure policy priority. I highly
recommend creating an Administrator policy the disables all policy and gives full
control to a select group of Citrix administrators to the top of the policy list to
prevent from locking yourself out.
In order to view the priory of Citrix Policies you set the consoles view mode to
Details. Select Details on the View menu Click the Priority section of the title bar
to sort by priority.
Important! User Policy settings override all other MetaFrame XP and Terminal
Services settings. However, if you disable functionality in Citrix Connection
Configuration, you cannot enable the functionality by creating user policies
How to Create a New Citrix Policy
The following details how to create Citrix User Policies
Open the Citrix Management Console, right click on the Policies section and click
Create Policy


Enter a name for the new policy and click OK.

Adjust the policy priority by clicking up or down priory buttons located on
the toolbar.
You have now sucessfully created a Citrix Policy and are ready to configure the rules
and assign user(s) / group(s) to it.
How to Configure a Citrix Policy
The following details how to configure policy rules.

Double click on a Citrix Policy to open the policy properties.

Click the policies that the rules you would like to set and click OK when
You have now successfully configured a Citrix Policy and are ready to assign the
Policy to user(s) / group(s).
How to Assign a Citrix Policy to User(s) and or Group(s)
The following details how to assign a policy to user or groups.

Right click on the policy you would like to assign user and or group to and click
Assign Users.


Select the User(s) / Groups(s) you would like to assign to the policy and click OK. I
highly recommend sticking with group to simply policy management. However if
you need to assign a user then you will need to check the Show users checkbox.
The Citrix policy will now be assigned to the designated user(s) / group(s) next time
they login to the MetaFrame farm.
1) First try to launch same application from Citrix server(on which you installed and
2) Try to add same application to your ID and try to launch
3) Check user permissions for that Applications
4) Verify that latest Citrix client software installed at desktop
5) Verify that user is having correct proxy settings to connect to your Citrix network
(for remote users)
13. What is ICA and what are the advantage of ICA

14. What is Speed Screen

15. What are the query command in citrix
16. What are the different ports use in Citrix
Some Citrix Port Numbers
1494: This port is used by any client using the TCP protocol to communicate with
the Presentation Server. You will need to open this port on your firewall for inbound
connections unless you are using some form of encapsulation or encryption. You can
change the port using the ICAPORT command but I find it to be more trouble than it
is worth.
1604: Called the ICA Browser port this is a UDP port that can be used by the
Program Neighbourhood to enumerate applications. You probably won t use this
80: This is the default port used by the XML service and is used by clients who
enumerate applications with the TCP+HTTP or XML protocol. You will thus need to
open this port on your firewall for inbound connections if clients will be using it to
locate servers. You can change the port easily enough using the CTXXMLSS
443: This is the default SSL. The SSL Relay will use it to secure communications
between the Web Interface and the server farm. You could also use it to secure
client communication to the web Interface or use it for client connections to the
Presentation Server.
5000: The Presentation Server uses this port to communicate with the IBM Db2
server hosting the data store.
1521: This port is used to communicate with the Oracle data store.
1433: The port used to communicate with a Microsoft SQL data store.
2512: This port is used for server to server communication such as when load
information is communicated. The port used to access the data store is saved in the
HKLMSOFTWARECITRIXIMAIMAPORT key on the server containing the data store. All
other servers use the port number saved in
HKLMSOFTWARECITRIXIMAPSSERVERPORT key in the registry to access the data
store. Have a look at IMAPORT to see how to change it.

2513: This port is used by the Presentation Server Console when connection to a
server. Have a look at IMAPORT to see how to change it.
2598: This is the session reliability port number and needs to be opened on your
firewall if the ICA Clients will be using session reliability when communication with
the server.
27000 and a random port number: This is the port used for communication between
the Citrix License server and the Presentation Servers. Remember that the Citrix
vendor daemon running on the license server uses a random port. It tracks license
version wise
18. What are the console available to manage citrix server.
Access Management Console
Presentation management console
Citrix web console
19. What is WebInterface or Nfuse
(Nfuse is the web interface of the citrix server).
Citrix Access Gateway is a universal SSL VPN appliance that combines the best
features of IPSec and typical SSL VPNs without the costly and cumbersome
implementation and management to make access easy for users, secure for the
company, and low-cost for the IT department. The Access Gateway provides a
secure, always-on, single point of access to any information resource. It works
through any firewall; supports all applications and protocols, including IP telephony;
is fast, simple and cost-effective to deploy and maintain via its Web-deployed, autoupdating client; and ensures that devices meet company security standards with a
worm-blocking client and integrated end-point scanning. The Access Gateway
automatically and seamlessly reconnects users to their applications when they
change locations and devices, and gives them the same access experience they
have at the desktop.
Citrix Access Gateway provides secure access to any application hosted on Citrix
Presentation Server, as well as distributed Windows and UNIX applications,
direct-access Web applications, network file shares, data and collaboration services,
and even telephony services using VoIP softphones. With the addition of the
Advanced Access Control option, the IT organization can utilize sense and response

capabilities to not only provide or deny access to appropriate applications, but also
control the level of user action rights for each application or resource accessed.

28. What are the parameters of Resource Manager?
In your day-to-day management of your MetaFrame XPe environment, Citrix
Resource Manager will be one of your most valuable tools. Resource Manager (RM)
serves three purposes:

Real time monitoring of MetaFrame XPe servers.

Historic reports containing information about MetaFrame XPe servers.

A central repository of usage information and statistics across all servers in

your farm.

Real time monitoring allows you to view the status of different components of the
MetaFrame XP server. Each component (known to Resource Manager as a "metric")
is viewed via the CMC, and has a green icon next to it if everything is okay. If there
are problems, the icon will turn a different color, depending on what the problem is.
You can configure the system to send alerts to SNMP traps, email addresses, or
short message service pagers if problems occur. You can completely customize the
types, behaviors and thresholds of each metric in your environment.
In addition to displaying the live status of MetaFrame XPe servers, Resource
Manager can also be used to collect and store detailed data about individual
servers. A system snapshot is taken every 15 seconds, and a report can be
generated on any timeframe in the past 96 hours, allowing you to see exactly what
the condition of the server was at a specific time.
Finally, if you are using Feature Release 2, MetaFrame XPe servers running Resource
Manager can periodically send statistics and data to a centralized database. From
there you can generate reports about overall farm usage. You can even set up
pricing information and generate invoices based on which users accessed the

The newest version of Citrix Resource Manager has evolved quite a bit in the past
few years, even since MetaFrame XP was first released. For that reason, this section
addresses the Resource Manager component of MetaFrame XPe with Service Pack 2
applied. Since Service Pack 2 is free, you can use it even if you don't plan on using
Feature Release 2.

Technical Overview
Even though Citrix Resource Manager is fairly straightforward, there are several
components required to make it work. These components include:

Citrix Resource Manager software.


Farm metric server.

IMA data store.

Local resource manager database.

Summary database.

Database connection server.

Resource Manager Software. In order to use Resource Manager, you need to

ensure that the Resource Manager components are enabled when you install
MetaFrame XPe. If not, you can install them at any time by running the SP-2/FR-2
installation program. The Resource Manager software must be locally installed on
each MetaFrame XPe server that you want to monitor. This software extends the
functionality of the IMA service, allowing it to collect metrics on various server
Metrics. A metric is a component (and its associated parameters) that is
monitored, including the thresholds for changing the status of the metric and
sending alerts. Each metric has an icon that changes colors to indicate its current
status. Metrics are configured in the server farm and applied to specific servers or
published applications. Examples of the hundreds of metrics available include
current user load, CPU utilization, and number of published applications in use.
Farm Metric Server. The Farm Metric Server (FMS) is responsible for monitoring
the status of the metrics of all servers and published applications in the entire
server farm. This server actually controls the metric icons, changing their status as
conditions warrant. The FMS gets its information from the zone data collector, which
is updated every 15 seconds by each MetaFrame XPe server.


IMA Data Store. All Resource Manager configuration information is stored in the
IMA data store. This includes the metrics and their associated configurations and
thresholds, as well as alert parameters and which metrics are applied to which
servers and published applications. Just like the other information in the IMA data
store, each MetaFrame XPe server's local host cache contains its local subset of the
Resource Manager information from the IMA data store.
Local Resource Manager Database. While the Resource Manager configuration
information is stored in the IMA data store, each MetaFrame XPe server is
responsible for locally maintaining its own Resource Manager data. This data, stored
in \Program Files\Citrix\Citrix Resource Manager\LocalDB\RMLocalDatabase.mdb on
each server, is maintained for the previous 96 hours, with new data overwriting the
oldest data.
Summary Database. In Feature Release 2 environments, the summary database is
a SQL or Oracle database that stores long term information about server usage. You
can configure this data to be whatever you want, but most people store only a small
subset of the local resource manager data in the summary database. The difference
is that the summary database is used to store the data for weeks or months.
Database Connection Server. This server is responsible for receiving summary
data from all MetaFrame XPe servers and writing it to the summary database. This is
the only server that directly connects to the summary database.
Figure 16.2 (next page) shows how the various Resource Manager components work
together in the MetaFrame XPe environment.

Monitoring Servers and Applications
Everything in Resource Manager is monitored via the metrics that you configure.
After installation, default server metrics are in place so you can begin monitoring a
server immediately without any additional configuration.
How you view the current status of the metrics depends on which type of metric you
are interested in viewing. There are essentially two types of metrics: published
application metrics and server metrics. Obviously, the published application metrics
show information relating to each specific published application. They can be
viewed in the published application's area in the CMC (CMC | Published Applications
| Your Application | Resource Manager Tab). The server metrics, which contain
server-specific status and information, can also be viewed via the CMC (CMC |
Servers | Your Server | Resource Manager Tab).


Metric Status
When viewing metrics, each specific metric has an icon whose color corresponds to
the state of the metric. Each metric type, both for published applications and
servers, has six possible states, as outlined below:
Green. The metric is operating within its acceptable limits as configured in its
Yellow. The metric has exceeded the limits of the green state and switched to
yellow, having exceeded the time and value limit threshold you configured.
Red. The metric has exceeded the time and limit thresholds of the yellow state and
switched to red. Any configured SNMP, SMS or email alerts have been sent.
Blue. The metric has been added, but it has not yet been configured, so it can't
change color. This blue status will not change until you edit the properties of the
metric and configure it for use.
Gray (Paused). The metric has entered a "snooze" state, manually invoked by an
administrator. During this snooze period the metric will not activate any red alarms,
and yellow and red conditions will not cause the metric to appear in the watcher
window. However, during this snooze state, the metric is still active and it is still
collecting data. The metric will exit the snooze state and become green, yellow, or
red, after a preconfigured amount of snooze time has passed, as configured in the
metric's properties.
Black (Stopped). The metric has entered a "sleep" state, manually invoked by an
administrator. During this sleep period, the metric will not activate any red alarms.
Also, yellow or red conditions will not cause the metric to appear in the watcher
window. However, during this sleep state, the metric is still active, and it is still
collecting data. The metric will not exit the sleep state until it is manually "woken
up" by an administrator.

How many connections to servers in the farm can IMA process/keep at one
While there is no finite answer to this, there is a registry setting that limits the Host
Resolver to keeping only 512 open connections to hosts. This is very important in
large farm design, and it can be manipulated.
The connections to hosts in a zone by a ZDC do not last forever, and can be torn
down and re-established. It is important to farm performance that steps are taken in
the zone to limit this teardown/setup process from occurring, and bumping up the
registry setting alleviates this in zones with more than 512 hosts. The registry
setting is:
HKEY_LOCAL_MACHINE\Software\Citrix\IMA\Runtime\ MaxHostAddressCacheEntries

When Miami Inc designs their global farm, the ZDC setup is of the utmost
importance as the number of servers in each zone will grow over time to very high
levels. A thorough understanding of this setting and the following information is
Zone Setup and Information
What is the function of a zone?
Zones perform two functions:
Collecting data from member servers in the zone
Distributing changes in the zone to other servers in the farm
What is a Zone Data Collector (ZDC)?
Each zone in a Presentation Server farm has its own traffic cop or ZDC. A ZDC
may also at times be referred to as the Zone Manager. The ZDC maintains all load
and session information for every server in the zone. ZDCs keep open connections
to other farm ZDCs for zone communication needs. Changes to/from member
servers of a ZDCs zone are immediately propagated to the other ZDCs in the farm.
How does the ZDC keep track of all of the hosts in the farm to make sure
they are live?
If ZDC does not receive an update within the configured amount of time from a
member server (default 1 minute) in its zone, it sends a ping (IMAPing) to the
member server in question. This timeframe can be configured in:
If ZDC does not receive an update within the configured amount of time from a peer
ZDC server, it does not continually ping the lost ZDC. It waits a default of 5
minutes, which is configurable in:
