SYMPTOMS
After you apply the security hotfix (Sec-fix) or Windows NT 4.0 Service
Pack 3, which includes this hotfix, applications that use null sessions may
no longer work properly.
For example, after you apply the security hotfix to a Windows NT computer
running Cheyenne ARCServe 6.0, you may receive the following error message
when you attempt to schedule a job (for example, local, remote, backup, and
restore):
User doesn't have enough rights to do this
EC=5
CAUSE
The updated security modules for Windows NT no longer permit null sessions
to access the Windows NT registry.
RESOLUTION
Perform the following steps to resolve this problem:
WARNING: Using Registry Editor incorrectly can cause serious, system-wide
problems that may require you to reinstall Windows NT to correct them.
Microsoft cannot guarantee that any problems resulting from the use of
Registry Editor can be solved. Use this tool at your own risk.
- Run Registry Editor (Regedt32.exe).
- Go to the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameter
- Add "winreg" (without the quotation marks) to the NullSessionPipes
entry.
- Restart your computer.
