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
