Thanks for such a concise reply.
The plotter is acting as a local printer with our current set up and I have a admin. PMP on my desktop. Each of the users has the client. They do get a pop-up asking them to pick the job but its isn't billing the jobs they pick. The plotter is picked up by the software but only users on my machine are shown in any field. Other users on our router network are not.
Sounds like from what you say I need them to connect to the plotter via the router rather then thru my machine. When I do that though they by-pass the admin. software and get no pop-up at all.
Then were can I put the PMP access file? It has to go on one of our machines since we have not true server. This was so much easier when we had a true server.
