NT 4.0 Printing

I have an NT 4.0 network. My clients are running win98 se. One of my clients all of a sudden quit printing to a network printer. It has worked for years. They were trying to print something for the Internet when it quit. I get the error that the path doesn’t exist for this printer. I have 10 other computers pointing to the same path and they work just find. Also any new computers get the same error. I’m unable to attach any new clients to this printer. Everything seems to be installed right. Like I said it has been working for years and all of the other Workstations print to it just fine. It is only these two computers.
