We have one 2003 Domain Controller and a Server 2008 R2 Exchange 2010 Server. The Exchange System Attendant service will not start. When I open up Active Directory Users & Computers on the Exchange Server (not a DC) - go to Domain Controllers, select properties of the DC and select the "Member of" tab - it tells me that the GC is not available. I added a 2nd DC - this time a 2008 R2 Server and GC. When this Server is on, the Exchange Server can find the GC and the Exchange System Attendant service can start. When this Server is off - it can't. The GC seems to replicate fine from the 2003 Server to the 2008. How do I troubleshoot the 2003 Global Catalog problem?

I have checked to see if any DCs are excluded in Exchange - no exclusions: http://support.microsoft.com/kb/298879 We don't want to keep the 2008 R2 DC (for now). We want the 2003 DC Global Catalog working correctly with Exchange 2010.

Check your Application event log for event id 2080. What DCs show up in the list? What's different with the 2003 DC? When 2nd DC is off: FILESERVER.CPI CDG 1 7 7 1 0 1 1 7 1 CPIDC.CPI CDG 1 0 0 1 0 0 0 0 0 When 2nd DC is on: FILESERVER.CPI CDG 1 7 7 1 0 1 1 7 1 CPIDC.CPI CDG 1 7 7 1 0 1 1 7 1

I ask because neither of them is a PDC FSMO role holder according to that information. Both of the DC's appear to be GCs, but that doesn't necessarily mean they're both functional. If CPIDC.PCI is the 2003 DC you might want to remove it as a GC and reboot it. After a few minutes promote it back to a GC and let it replicate, then reboot it again. If you still have problems after that try running ExBPA and see what it has to say. DCDIAG and NETDIAG may also shed some light on your problem, but i don't think it's an Exchange problem. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
