How can I enable strong protection on shared system objects?

A. It is possible to tighten security on shared system resource attributes, such as the attributes of COM1: or of printers. By tightening base security, these shared resources will be administered only by system administrators.

To enable this perform the following:

  1. Start the registry editor (regedit.exe)
  2. Move to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager
  3. From the Edit menu select New - DWORD value and enter a name of ProtectionMode if it does not already exist
  4. Double click the value and set to 1. Click OK
  5. Reboot the computer

After performing this change you should update your Emergency Repair Disk using RDISK.EXE.
