I installed a printer via a usb connection to the Windows xp machine, shared it and make Windows xp the print server.

When connecting from remote client via \\print-server\printer I get a prompt for the login box. After entering the administrator login and password, I could print. How could I change it so the users does not have to enter the username and password?

I think there is something needed to be changed in group policy. Thanks for any help.
