Users cannot log into second domain controller when the first is down.
Posted on 2011-09-22
I have a Server 2003 R2 network with two Server 2003 R2 domain controllers and three Server 2003 R2 terminal servers running Presentation Server 4.5. When my first DC is down my TS server users get logged out of Citrix and cannot get back in until the primary DC comes back up.
I have confirmed that all three terminal servers have both the primary and secondary domain controllers listed in DNS and the DCs, themselves are communicating. When I make a change in AD one one it is replicaticated to the Active Directory in the secong domain controller.
How do I allow my users to default to the second domain controller in the absence of the first?
