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 Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
