So I was helping this guy I know fix his printer problems..He has this w2k PC w/ an HP printer hooked up...He wants to print from a networked XP PC...So I can add the printer in XP..Only if I supply a username/password. It's Administrator and no PW..So it adds..Then prints fine..Need to restart the computer? Well, if that happens the printer is no longer connected and access is denied from the w2k computer. Huge pain in the arse. No idea why.. The only way to print again is to delete the printer, restart and add it manually again..I know it MUST have to do with users/permissions on the w2k PC..But the EVERYONE acct is active w/ all permissiones,etc..also another XP PC prints FINE from this HP printer..Any idea why a previously usable printer would be rendered unusable by a restart?

TIA
