Question : Error event occuring since bringing up new HubCAS sever

Trying to set up a multi-site CCR Exchange server environment. HubCAS server has been installed but I am receiveing this error "Microsoft Exchange System Attendant failed to read the membership of the unive rsal security group '/dc=net/dc=swfwmd/ou=Microsoft Exchange Security Groups/c n=Exchange Servers the error code was '8007203a"

Answer : Error event occuring since bringing up new HubCAS sever

This was found to be caused by old login references to some 2003 DCs that were no longer in our environment due to upgrading to all 2008 DCs. Once I restarted the Exchanges servers after all 2003 DCs were demoted, this error no longer appeared.
Thanks
