The Net Logon Service of a Windows NT 4.0 BDC Does Not Function In a Windows 2000 Domain (Q293127) To resolve this behavior, change the setting for the RestrictAnonymous value from 2 to a 0 on the Windows 2000 domain controller that hosts the primary domain controller (PDC) emulator operations master role.
