Forcing Domain Logons in Win98

But can't the user still select the "cancel" button to bypass logon
completely?  I've never heard that one could secure a Win95/98 box.

Ooo! Oooo! Ooooo!  This is my **favorite** hack!

Use a resource editor (one comes with VC++) and open
the mprserv.dll library in it.  You must edit the
file when running Windows NT as Windows 9x does not
support writing change to a binary file.  Now disable
the DOMAIN field in the Windows network logon dialog.
This will prevent changes except by modifying the
registry settings.

Hope this helps,
