Join Now. We have a remote site with 30 Domain users, we have a Power Edge 2900 with 4 gb Memory running Windows Server 2003 Operating System. We are planning to add a new Domain Controller and keep the existing one as a secondary domain controller. Users are also using the domain controller as a file share server.
You have to add a domain controller to your network when you decide that it is cost-effective for your organization to have the unified system of credentials, users, groups, and permissions that an Active Directory domain provides, in addition to the machine and user policies provided by Group Policy.nce a domain controller is configured in a company, office or a building, it takes over the responsibility of responding to usersâ security authentication requests, such as checking permissions, logging in, etc. When a client computer joins a domain, any user can login to the domain controller, using that computer.
