I was presented with the following scenario:
1. User had Win2K Server PDC and bought new server.
2. Win2k3 Server has been installed to new server (connected to PDC). Migration ran smoothly (apparently).
3. User was advised to keep old server up and running for some time to make sure everything was ok.
4. User shutdown old server by it’s own a few days later (that was several weeks ago).
Now, when trying to create new users, OS says it cannot contact the global catalog is not available. It creates the user but it states that it cannot be sure if the user already existed. TS and XP users are not authenticating any more (just Win98 users).
It seems to me the the migration also didn’t migrate at least the schema master (other objects might not have benn migrated as well).
Can I simply remove the old server from the domain and increase domain functional level (it’s in mixed mode and the only option is native)? Will this solve the problem?
Thanks!
