I'm building a CCR cluster and I already implemented many others, but on this situation I'm getting an issue saying that setup failed because the cluster group was not found... "cluster resource group for clustered mailbox SERVER was not found";The cluster is already formed with two nodes and it's working fine - FSW inplace and working fine also.The setup fails at alsmost at 100% of the setup so I would like to know which information should be good to check on this cases, because I don't have much more info at exchange setup log or in the event viewer.Thanks

Hi,Is this the issue that you are experiencing?http://blogs.technet.com/thbrown/archive/2009/08/05/ccr-install-fails-with-0x8007139f.aspxLeif

Actually not... first I'm using Windows 2008 and the error I'm facing is the below:[1/6/2010 1:43:04 PM] [2] Previous operation run on domain controller '<ADSERVER>'.[1/6/2010 1:43:04 PM] [2] [ERROR] Unexpected Error[1/6/2010 1:43:04 PM] [2] [ERROR] Cluster Common Failure Exception: The cluster resource group for clustered mailbox server <CMS_NAME> was not found.[1/6/2010 1:43:04 PM] [2] Ending processing.[1/6/2010 1:43:04 PM] [1] The following 1 error(s) occurred during task execution:[1/6/2010 1:43:04 PM] [1] 0.

Cheers

Hi,Did you try to create the group as explained in my first post and see if that helps?Leif

Please try to the method in the post of this threadJames Luo TechNet Subscriber Support (http://technet.microsoft.com/en-us/subscriptions/ms788697.aspx) If you have any feedback on our support, please contact tngfb@microsoft.com

I tried that but didn't work as well...I double-checked the permissions on cms computer object and found all ok; cluster computer account (MSCS_NAME$) with full control (computer account because this cluster is formed with windows 2008);Cheers

hi , first tell me is ur domain controller on windows server 2003.if yes delegate the computer account fromed by the cluster read & write permisson in the active directory.& make sure that this computer account is in local admin on the 2 cluser nodes.
