We have an Aficio mp5002 copier on our Server 2003/XP Pro network.
I can grab an IP address (I reserved it one).
I've installed in on the server and shared it.
I've "connected" it to our workstations.
The workstations can ping it IP but cannot print to it.
The print log shows "authentication error occurred" for each print attempt.
We're never prompted for a password...
