I have a new 2008 Standard server.
I have an old 2000 Server that is the only domain controller.
I've added the 2008 server. I get part way through the processing of setting up the FMSO services on the 2008 server and then start getting errors. The errors indicate it can no longer communicate with the domain controller.
Example: If I go into AD Domains and Trusts, right-click and select Change AD Server, the Look In this Domain is blank. I click the down arrow to display the list and I get "The list of Domain Controllers for domain ABC.com is unavailable because: The server is not operational."
The only DNS server I have specified on the 2008 server is the IP for the 2000 server.
10 minutes I was able to go into AD Domain and Trusts on the 2008 server. I also went into AD Users and Computers and could see all the users and computers that had replicated.
The 2000 Server has the following event IDs & Source in the System Log (in this order from oldest to most recent):
5723 NETLOGON The session setup from the computer W2008 failed because there is no trust account in the security database for this computer.
5790 NETLOGON (description cannot be found)
36872 SCHANNEL No suitable default server credential exists on this system...
5722 NETLOGON The session setup from the computer W2008 failed to authenticate.
