JSI Tip 7818. After restricting remote access to the Windows 2000 registry, remote access is still possible?

After implementing the restrictions in the following Microsoft Knowledge Base articles, remote access to the registry is still allowed:

153183 - How to restrict access to the registry from a remote computer.

143474 - Restricting information available to anonymous logon users.

This behavior is indicative of having the RestrictNullSessAccess Value Name, a REG_DWORD data type, set to 0 at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters.

To workaround this behavior, set the data value of RestrictNullSessAccess to 1.
