Windows NT has a feature where anonymous logon users can list domain user names and enumerate share names. Customers who want enhanced security have requested the ability to optionally restrict this functionality.
1. Run Registry Editor (regedit.exe).
2. Go to the following key in the registry:
3. On the Edit menu, click Add Value and use the following entry:
Value Name: RestrictAnonymous
Data Type: REG_DWORD
Value: 1
4. Exit the Registry Editor and restart the computer for the change to take effect.
Note: It is only possible to control this operation after installing Windows NT 4.0 Service Pack 3 or the Windows NT 3.51 hotfix.

Key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\LSA]
Value Name: RestrictAnonymous
Data Type: REG_DWORD
Data: (0=disabled, 1=enabled)
