Welcome to the board.
I'm trying to wrap my mind around your password scheme. Are you saying you want to change the local administrator password every day? Isn't that sorta overkill? You could change the password, but I'd advise it be done from an admin script and not the logon. There are permission issues with doing it in the logon. Also, you would want to record the change otherwise you'd have no idea what the password is. If done within the logon, the user would have access to the log file and could mess with it.

I assume the local administrator accound is not used and that users are not in the local administrators group.

Are these machines NT4 or W2K or XP? If NT4, do they have ADSI Provider installed?
