Tried HP LaserJet P2015 from cd with network disconnected; Setup starts, runs for a minute, then provides error stating you should try the "Run as admin". Restarted, tried to run setup manually WITH Run As - no change - Darned!
When the machine is connected to the wire, do not have to right-click, run as - Runs fine, normal...
With cable unplugged, right-click, Run as Administrator fails. Consistent across 3 machines now. STill haven't had a chance to try other printer software.
OK, but I just got to know....how does it fail? Do you get an opportunity to enter a username and password? And if so do you use the fully qualified domain username like email@example.com or does it just do nothing?
"Does nothing" would be the answer; User is not prompted to enter anything, doesn't have a chance to enter anything. Not prompted to enter a admin password, or user/password combo. I'm guessing because they are in the Administrators group already??
