SYMPTOMS
With User Manager, when you attempt to add users or global groups from a trusted Windows 2000 domain (on a Windows NT 4.0 domain controller) to a local group in the Windows NT 4.0 domain, you may receive the following error message:
Also, you may observe in User Manager that existing users and groups from the Windows 2000 domain, which are members of domain local groups, are displayed as "Account Unknown."
CAUSE
This behavior can occur because the RestrictAnonymous registry value is set to Level 2 on the Windows 2000 domain controller on which the Windows NT 4.0-based computer has its secure channel.
RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
To resolve this behavior:
- Set the RestrictAnonymous registry value to 0 or 1 on the Windows 2000 domain controller. This registry value can be found at:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa
Value: RestrictAnonymous
Value Data: 0x1 or 0x0(Hex)
Value Type: REG_DWORD
- Restart the domain controller.
- Break, and then reestablish the trust.
MORE INFORMATION
The RestrictAnonymous registry value with a Level 2 setting must only be used in "pure" Windows 2000 environments.
