I have a network running from a domain set up on a Windows 2003 Server, and three workstations running XP Professional. Workstation 1 has a printer which is shared across the network. Workstation 2 sees this printer and works perfectly. Workstation 3 sometimes refuses to connect to this printer. If I reboot it, it connects to the printer and works for "three to five days" before it goes out again. When it's not working, you can go to Printers and Faxes and see the printer status listed as "Opening..."
I've checked the printer permissions, and it's set for everyone to have full control of it, and there doesn't seem to be a login required on Workstation 1 to access the print share. I've bypassed problems like this for shared network drives in the past with the NET USE command, but don't know if I can use the same trick for a printer.
If it makes a difference, Workstation 3 used to run XP Home Edition, and was later upgraded to XP Professional.
Thanks for any suggestions you can give,
