Problem: On startup, when logging in as non-admin, our Vista computers require administrator credentials to install network printers. We would rather the printers install without our intervention like they do for the XP computers here.

Details: The script we are using (rundll32 printui.dll,PrintUIEntry /in /q /n \\server_name\printer_name) is pushed out via Group Policy. When a non-admin user logs in for the first time this is what happens: he gets an pop up message containing a yellow triangle with an exclamation mark in it and reads: "To use the shared printer \\server_name\printer_name, you need to install the printer driver on your computer. If you do not recognize or trust the name and location of the printer, do not install the driver." Then it gives me the option of 2 buttons: "Install driver" or "Cancel". Cancel obviously just quits the printer install. "Install driver" dims the screen and puts up a UAC window stating that an administrator username and password are required to continue. If I put in my admin credentials, it installs the printer and then never bothers the non-admin user again when they reboot.

That may not sound so bad at first glance but we have 50+ Vista users, each requiring about 4 new printers to be installed very soon. So as you can see, this process would be very time consuming and not very fun for our IT department.

I'm hoping someone has figured this out and can lend a hand. I'm game for tweaking the script as long as it will work for XP and Vista (and ideally Windows 7).
