LSASRV Event Log errors, EventID 40960

Last Modified: 2012-05-08
On our member server (not a DC just fileserv'ing), just started getting some LSASRV 40960 errors in the event log:
The Security System detected an authentication error for the server cifs/<server FQDN>.  The failure code from authentication protocol Kerberos was "The attempted logon is invalid. This is either due to a bad username or authentication information.
It's happening every hour or so and there is a seperate entry in this file servers log for each DC in the forest, including the DC in our child domain.

The domain admin password was changed recently so i THINK it has something to do with this, if that's the cause then i can't figure out what app or service on this server is trying to authenticate with the old password.

Any ideas on which service/app is causing this and how i can update the credentials its using or even if this is the cause?

On the actual DC it doesn't have this issue.
