title: Domain Suffix added to DNS Queries
body: <p>I have a reoccurring DNS problem that has been plaguing our users, occasionally causing their laptops to append our company's domain to the end of all DNS queries.  The problem only occurs when users are off site and it appears to be fairly random.  It will work one day and then, out of the blue, it will show the invalid entry.  This effects mostly Windows XP users but has recently been seen on Vista as well.  Here is an example using nslookup.</p>
  
  <p>C:\Users\Username>nslookup www.yahoo.com
  Server:  Linksys
  Address:  192.168.0.1</p>
  
  <p>Non-authoritative answer:
  Name:    www.yahoo.com.MYDOMAIN.COM
  Address:  999.999.999.999</p>
  
  <p>I have replaced the IP address that is reported with a placeholder but I can tell you that what it returns is the default *. entry on our Network Solutions configuration. Since obvious www.yahoo.com.MYDOMAIN.COM doesn't exist this makes since.  I believe the users internal equipment is functioning properly.  Internally we run a Windows 2k3 Active Directory w/ Windows based DHCP and DNS servers.  Eventually the problem resolves itself usually over a couple of hours or a number of reboots.</p>
  
  <p>Has anyone seen this behavior before?</p>
