On my initial deployment I succesfully installed CCR mailbox roles. I uninstalled to make some storage changes now I'm receiving this error whne trying toreinstall CCR. I have no users yet, HT and CAS are installed on a different server. Can anyone help me get this going again? Summary: 3 item(s). 2 succeeded, 1 failed. Elapsed time: 00:03:55 Copy Exchange FilesCompleted Elapsed Time: 00:00:14 Mailbox RoleCompleted Elapsed Time: 00:03:29 Clustered Mailbox ServerFailed Error:The operation could not be performed because object 'servername' could not be found on domain controller 'domainName'.

This sure sounds like a DNS issue rather than a CCR issue. You completely un-installed CCR just to make some storage changes? You probably did not need to do that, but here we are. When you see the message you are seeing, what exactly are you doing? One thing to check is to make sure that the CCR's clustered mailbox server (CMS) name is registering properly in DNS. I remember something about this when I have installed E2K7 clustering in the past, but I think I created the DNS name and IP for the CMS manually in DNS.

Please also check the ExchangeSetup.log and Event Logfor further information. Verifying an Exchange 2007 Installation http://technet.microsoft.com/en-us/library/bb125254(EXCHG.80).aspx Mike

Gil, Did you ever get a resolution to this issue? I have the exact same problem... Hope you can be of some assistance. Thanks!

Hello, We had a similar problem and we managed to make it by disabling the security on the DNS zone. This was indeed a very time consuming problem. Laurent
