SYMPTOMS
If a user on a computer that is running Microsoft Windows 95 or Microsoft Windows 98 attempts to log on to a Windows 2000-based domain and is validated by a domain controller that has that user's account locked, but the primary domain controller operations master (also known as flexible single-master operations or FSMO) has the account unlocked, the logon attempt is denied.



CAUSE
The validating domain controller, if it is not the primary domain controller operations master, checks with the primary domain controller for the account lockout status and finds the user account unlocked, but does not handle the logon attempt correctly and denies the attempt even though the attempt should succeed.
