this might be a clue to how winlogon.exe was run.

Winlogon is a native process (as opposed to a Win32 process). It runs early in the boot process. As someone else noted, the path you saw is normal.

It *does* have a DLL, MSGINA.DLL; this gets the logon info from the user for Winlogon. It's designed so that third-parties can use, say, a biometric MSGINA in place of the usual prompt.

Next question is if it's possible for MSGINA to be co-opted?

"Inside Windows 2000" is the best investment any Windows admin can make, next to the RK.

Take care,

Dave
