Incorrect Permission in Registry Cause Unpredictable Results
ID: Q139342
 
 | 
The information in this article applies to:
- 
Microsoft Windows NT Workstation versions  3.5, 3.51, 4.0
- 
Microsoft Windows NT Server versions  3.5, 3.51, 4.0
SYMPTOMS
If you have incorrect permissions set in the Windows NT LanmanServer
registry keys, unpredictable results occur. Following are some examples:
- A member of the Administrators group is denied access to
   create a new share, or stop sharing an existing share.
- Users on remote clients are not able to connect to or view
   shares.
- File Manager stops responding (hangs) when the Sharing or
   Stop Sharing buttons are pressed.
- Windows NT Server takes an extraordinary long time to
   restart (as much as 10 additional minutes).
- The System Profile loads including its usual configuration
   such as a bitmap if one is defined and a mouse pointer, but
   the Winlogon Welcome dialog box (normally displaying "Press
   Ctrl+Alt+Del to log on.") is not displayed.
- Windows NT does not boot at all.
MORE INFORMATION
By default, the LanmanServer has the following Permissions:
   Administrators   Full Control
   System           Full Control
   Everyone         Special Access
                    Query Value
                    Create Subkey
                    Enumerate Subkeys
                    Notify
                    Read Control 
To verify or change these Permissions, run the Registry Editor
(REGEDT32.EXE).
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.
From the HKEY_LOCAL_MACHINE subtree, go to the following key:
   \SYSTEM\CurrentControlSet\Services\LanmanServer
