Hi, We have Exchange 2007 A/P 2 node SCC cluster setup with Exchange 2007 SP1. Recently due to the AD corruption I have restored the AD from the backup (This Backup was done while upgrading mailbox clusters to the SP1). After the backup I had to rebuild the SYSVOL folder. Now everything works fine except a couple of issues. Issue 1: Whenever I try to move mail box cluster from exchange management console; in the select target machine window, only one node is displayed... even if we search for the other node, it wonât display the other node. Issue 2:- whenever we move a cluster to other node, one warning followed by an error is being noted in application log.

If you one of your node is not in your AD (can you clarify if it is in AD?) from the snapshot of your AD restore, you will have to effectively put it back into place. Keep the CMS on the working node then install the passive mailbox role onto the 'unknown' node. Disaster recovery (/recovercms) will not work here as there is no information to pull from Active Directory. Oliver
Dear Oliver, Thank you for your reply... In the snap shot of backup ; both the nodes are in AD, only Exchange SP1 installtion was going on that moment. Please let me know what to do in that case.... And also Please let me know why I was not able to see the other node in "move mail box cluster" wizard whlle moving the cluster from other node... I also noticed below errors when I restart any node... Can you please comment on this as well...

Hi again, Having the second node exist in AD as a Computer Account doesn't mean it is part of the Exchange topology. In Powershell run: Get-mailboxserver -identity yourCMSnamehere |select redundantmachines Does it list both nodes? Oliver
