Exchange 2007 SP2 Setup fails if all DCs are running WS08 R2
Microsoft Exchange Team Blog has recently posted the following information:
“We have learned of and analyzed the problem where the Exchange 2007 SP2 installation can fail during the prerequisite check stage. The installation can fail for both the upgrade or for new installation of Exchange 2007 SP2.
In the Exchange Setup log you can see that setup is failing with the following error:
[ERROR] Cannot find at least one domain controller running Windows Server 2003 Service Pack 1 or later in domain ‘DC=DCName,DC=com,DC=DCName’. This could be the result of moving domain controller objects in Active Directory. Check that at least one domain controller running Windows Server 2003 Service Pack 1 or later is located in the ‘Domain Controllers’ organizational unit (OU) and rerun setup.
This can happen in the following scenarios:
* You are installing or upgrading to Exchange 2007 SP2 in an Active Directory forest that has only Windows Server 2008 R2 Domain Controllers,
OR
* You are installing or upgrading the Exchange 2007 SP2 in an Active Directory forest that has windows server 2008 R2 Domain Controllers as well Windows Server 2003 domain controllers that are not updated to at least Windows Server 2003 SP1.”

What if I am just trying to install Exchange 2007 NO SP. My DC is Windows 2008R2.
I am not upgrading just trying to install for the first time.

Dave, have you tried installing Exchange 2007 with no service packs? Considering how Microsoft is discouraging people from running Exchange 2007 on Windows Server 2008 R2 (they want you to install Exchange 2010) I have never tried that and frankly I am not sure if you will be able to install Exchange 2007 without any service packs on Windows Server 2008 R2. You should be running the latest service pack anyway. A lot of people are having issues installing Exchange 2007 even with Exchange SP1 and SP2 on Windows Server 2008 R2.
