WinXP SP2, ZfD 7 client on the box, no client32--just the ZfD client. (I
know, why are you posting in this forum? 'Cuz i think the problem would most
likely be fixed in the Client32 forum).

After a seemingly successful ZfD client removal from add/remove programs,
the subsequent reboots show to be problematic. Rather than the usual XP
login window popping up, we get generic window with a "User Interface
Failure" heading with text that says "The Logon User Interface DLL
NWGina.dll failed to load. Contact your system administrator to replace the
DLL or restore the original DLL".

The only option is to click on Restart.

How does one fix this problem w/o reinstalling Windows?
