I was wondering if anyone has experienced an issue where certain user accounts lockout for no apparent reason. The security logs show activity that seems to be associated with the kerberos ticket for the user and computer. I have checked TechNet andcan?t find a solution that works. I have installed W2KSP2 but it has not resolved the issue.

Q261007 explains this behavior can occur on the workstation if the address for the configured preferred DNS server on the client is invalid or unreachable. Well, itis configured and reachable.
I wonder if the two are related? Can anyone help me?
