UAG 2010: Error "Unknown error 0xc00000403" when adding UAG machine to a Array

You may encounter the following error while joining an array member to a UAG array.


Cause:  After entering username, password and Domain UAG Array Manager machine verifies  these credentials with the Domain Controller using kerberos. After successful verification, it allows member to join the array.  But if  Kerberos communication between the domain controller and the UAG server fails, then the credentials will not be verified and UAG throws the above error.

Soultion: Restart either DC or UAG Array Manager or both. It may re-establish Kerberos communication between DC and UAG and thus credentials can be verified sent by member machine.
