This article was previously published under Q143138 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.

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

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.
