I have Exchange 2010 running on 4 servers, 2 hub/cas and 2 mailbox servers. I installed all the servers with Exchange 2010 SP1 and recently updated to SP2 about a week ago. Today, I dismounted the databases to troubleshoot an issue with logs not being truncated. I attempted to mount them again but none of them will mount. For each one, I get the following:<br />
<br />
Active Directory operation failed on XXXX This error is not retriable. Additional information: Directory object not found.<br />
Active directory response: 0000208D: NameErr: DSID-031001CD, problem 2001 (NO_OBJECT), data 0, best match of:(domain.com)<br />
<br />
Everything was working fine prior to the dismount.<br />
