I am attempting to help a colleague who is having the following issue: On a Windows network, users who are attemting to print to a network printer from any of their new XP machines are asked for a printer password, UNLESS they have Admin rights to the worstation. No printer password has ever existed. Any ideas would be greatly appreciated.
