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.

After you install the hotfix, the following DWORD registry value is checked to determine if NDS "Members" should be used instead of NDS "Security Equivalent To Me" for group memberships:
It the data value is set to 1, MSDSS uses the member attribute. If the data value is set to 0 or -1 (or does not exist), MSDSS uses the "Security Equivalent To Me" attribute.
