Require a Windows 9x logon

Even though Windows 9x/Me may present you with a prompt to enter a username and password, you likely know that this can be easily bypassed. If the machine belongs to a network with a Windows NT/2000 domain, you can force Windows 9x to require proper authentication with the network in order to logon. It's a simple registry tweak as follows:

  • Run Regedit
  • Navigate to HKEY_LOCAL_MACHINE Network Logon
  • Right click on Logon and select "New"
  • Left click on "DWORD Value" and type "MustBeValidated" (without the quotation marks)
  • Then hit on the keyboard
  • Right Click on "MustBeValidated" and select "Modify"
  • Change "Value Data:" to 1 and select "OK" (0 would not require validation)
  • Reboot the computer

    Windows 9x will now require proper authentication with the network in order to logon.
