We currently have an SBS 2003 domain. I wasn’t part of the initial setup of the domain but am more or less the administrator now. We use SBS for domain controller duties, as a file share server, and a local Sharepoint site. The SBS install also has an Exchange install included, but we are not interested in maintaining that in the future. Actually, we aren’t really even needing to migrate Sharepoint either since that isn’t really used much anymore.

We want to migrate to a Windows Server 2008 R2 environment. We have a new server with a fresh install of Server 2008 and the intent is to add this to the domain as a second controller, migrate everything we need over, and finally decommission the SBS server.

I followed the “Dematzer’s Blog” entry for migrating SBS 2003 to Windows Server 2008 R2, ignoring the part about Exchange, and everything seemed to work until these steps:

  • Transfer all 5 FSMO roles to Windows 2008 Domain Controller

  • DCPROMO SBS 2003 server so it is no longer a domain controller and
    remove from network

The FMSO roles seemed to work, or at least they said they didn't throw any errors, but the DCPROMO part said it couldn’t find another domain controller on the network when we tried to demote the SBS server. Everything looked like it was set up the way it needed to be but I think there was a problem with the replication or something...on the new Windows Server I thought it was able to manage the domain but if I shut down the SBS server none of our workstations were able to connect. It’s like the new server was just superficially set up as a domain controller.

I think I have a couple of questions/issues. I think one of the things might be related to DNS. How should DNS be set up in what I’m trying to do? Before starting, the SBS server was the DNS server for everything. The SBS server itself had entries for our ISP servers as it’s DNS.

If it’s a replication issue - how does it occur, how can I tell if AD replication has occurred, and how can I force a replication rather than waiting for some amount of time?

I have the output from DCDIAG I can post if it would be useful. The ipconfig settings are here, although I notice now that each DC is pointing to the other as it's DNS server. "psgsrv1" is the SBS server, "GENE" is the new 2008 server:
