I have a Windows 2003 Server print server setup to handle all our network printers/copiers. In the last few months I've had two printers unexpectedly become unreachable to end users. I was able to print test pages from the print server, but workstations could not access this printer. I re-installed the print driver and that seemed to fix one of the printers. If I recreated the printer/share, they would work as well. Unfortunately I still don't know why this would occur. I'd appreciate any ideas or suggestion on how this might have occurred and ways to avoid it down the line.
