Event Description: -
Comment: After introducing a Windows Server 2008 R2 domain controller to the domain, this error was repeatedly recorded in the new DC DNS event log.  Running dcdiag /test:dns on this DC produced a Connectivity failure with the error 0x621.  DNS records could not be manually added in the DNS snap-in, either.

The server is configured with NIC teaming for failover purposes.  Applying the hofix from Article 978387 and restarting the DNS service resolved these issues. Index: 0
