  • Urgent help: DCDIAG Errors after trying to remove GC

    Hi all

    I'm in quite a pickle.

    I was migrating from SBS 2003 to Windows 2008 R2 + Exchange 2010, following Dematzer's guide on EE.

    All was going well, til the last 2 steps.

    So the Windows 2008 DC is also a GC. I unticked the SBS2003 GC box and Exchange stopped working.

    Everything else seems to work ok still, user logons, file access etc.

    This was mid day, so i quickly reticked the SBS GC box, rebooted and everything seemed ok.

    Before I started, dcdiag on the Windows 2008 Server was all clean.

    Now everyone has gone home I tried it again with the same results. I had to again retick the SBS GC box and reboot. Except now, there continues to be errors on the 2008 server dcdiag.

    Exchange is working currently as far as I can see.

    Saints1 is the SBS, Saints-DC is the 2008.

    The 2008 Server holds all 5 FSMO roles, and the SBS is still a DC at this point.

    All Servers are on exactly the same time.

    How can I fix this and get shot of the SBS server?

    TIA

    OP was too long - this is the current DCDIAG on 2008 Server:

        Re: Urgent help: DCDIAG Errors after trying to remove GC

        What are the IP configurations of both servers? Sounds like they're having trouble communicating. At this point I would imagine that both machines should be on static IPs.

        I don't have a copy of the guide you referenced so I'm not sure what has been done up until this stage.

        Where is the DNS server at this point? If both servers still have DNS, check the event viewer logs for that to see if they're having trouble replicating.

        If DNS is still on the old server, make sure the new server isn't pointing at itself. If it has been moved to the new server, make sure the old server can use the new server for DNS.

        Also, just in case try turning off any firewalls or antivirus that may be getting in the way.

        Somewhere in the network configuration, pings, nslookups etc you should find some pointers. Event viewer on both servers might help out too.

          Re: Urgent help: DCDIAG Errors after trying to remove GC

          Hi

          I managed to fix it after a very late night.

          I went ahead and demoted the SBS, and turned it off to get rid of that from the equation.

          Needless to say it still didnt work after that.

          I dug through DNS and found rogue entries for the SBS server still there. Removed those, reboot and dcdiag suddenly looked much better!

          Exchange still wouldnt work though.

          That ended up being because I had disabled ipv6, and I was unable to reinstall it as it crashed ncpa.cpl. Tried many things, registry, removing and readding NIC's (VM), in the end sfc /scannow done it.

          Not quite understanding why IPv6 broke exchange at that point as I had uninstalled it about 4 days ago and the server has been fine.

          So yeah...immediate full backup and a good night's sleep!
