Hi all, long time lurker, first time poster.
An upgrade from SP1b1 to SP1b2 seems to be a bust at least on my system, keep getting this error at the org prep stage:
Organization Preparation
Failed
Error:
PrepareDomain for domain domain1 was unable to add the group CN=Exchange Install Domain Servers,CN=Microsoft Exchange System Objects,DC=domain1,DC=local to the group CN=Exchange Servers,OU=Microsoft Exchange Security Groups,DC=domain1,DC=local on domain controller DC.domain1.local, because the current user does not have permissions to modify Exchange Servers. Please ensure that the current user can modify the membership of Exchange Servers and run PrepareDomain again.
Active Directory operation failed on DC.domain1.local. This error is not retriable. Additional information: Insufficient access rights to perform the operation.
Active directory response: 00002098: SecErr: DSID-03150A45, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0
The user has insufficient access rights.
I'm logged on as Administrator and that account has all the rights in the world to do ANYTHING in the domain. Thought about trying to uninstall SP1b1 but doesn't seem like that's possible.
