A. It is possible to restrict the ability to list domain user namesand enumerate share names available to anonymous logon users (also known asNULL session connections). If you feel this is a security risk Service Pack 3for Windows NT 4.0 introduces a new option to stop anonymous users listingusers and shares.
To enable this perform the following:
Start the registry editor (regedit.exe)
Move to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlLsa
From the Edit menu select New - DWORD value and enter a name ofRestrictAnonymous if it does not already exist
Double click the value and set to 1. Click OK
Reboot the computer
After performing this change you should update your Emergency Repair Diskusing RDISK.EXE.
