Windows 98 Logon Security
I was just going through some old information I have and came up on this which I had forgotten about. In 98 a user can hit "cancel" or the "x" on the logon screen and still get to the desktop. With this easy reg fix you can disable that, and make them logon or they can't get to the desktop. The only loophole ofcourse is that you can get to the desktop in safe mode, but they won't know that:
HKEY_LOCAL_MACHINE\NETWORK\Logon
Create the following:
RegDWord named "MustBeValidated" (no quotes)
Set the value to:
Decimal with the value of 1
