I have 2 Domain Controllers in my Windows 2000 network. In the last couple weeks the two servers have stopped replicating with each other. I am only able to create new users on the Global Catalog server (server A), and these users do not replicateinto the AD on the other server (Server B). When trying to create a new user on Server B, I get the following error message: ?Windows cannot validate the uniqueness of this proposed user name with a global catalog server because: The server is notoperational. Windows will create this user account, but the user can log on only after the username is verified to be unique. For further assistance, contact your system administrator.?
Both servers can ping each other by IP address and Computer Name, and the servers are functioning fine otherwise. I have made Server B a Global Catalog server as well, this happened with no errors. Both computers have a Sysvol share.
Any ideas?
