Are XP Home 5 Concurrent Connections.
XP Media Center 5 Concurrent Connections.
Neither of these OS's can be added to a Domain,
XP Pro 10 Concurrent Connections.
This is the only version of XP that can be added to a Domain.
The problem here is that when other client computers connect to what is effectively a Print Server they do not relinquish their current connection so once 10 computers have sent 1 Print Job it becomes impossible to connect another computer to the computer with the Printer Attached. You need to restart either the computer with the Printer Attached or clear the Current connected computers.
Sometimes an existing computer that is already connected instead of sending a Print Request down the established connection attempts to open another connection and if the Upper Limit is already reached the Print Job Fails.
The permanent solution is to setup a Dedicated Print Sever with a Server OS in use not a Workstation OS.
