I have wired setup that I need to fix.
There are two physical locations: Location A with domain controller DC01 which holds all FSMO roles
Location B with domain controller EXDC01 which is GC
Exchange Server 2010 SP1 is installed on EXDC01 and it works fine as long as DC01 is available.
Somehow Exchange server is using DC01 for all settings (DC, CDC and GC)
If I point Exchange server to EXDC01 (itself) using static settings, it won't start services
In event log it complains it cannot talk to CDC.
I tested connection to that server using LDP and using telnet to all AD TCP ports and all works fine.
There are no configuration errors that I could find since I replicated environment in the lab and experienced same issue:
- Install DC01 - Windows 2008 R2
- Run dcpromo
- Install EXDC01
- Run dcpromo
- Install exchange server
