James- If UAC is not enabled, I'm not clear why you believe the GPP printer install is hanging because of the UAC prompt? But, a couple of questions-do these preferences have the option checked to run in the user's context? Have you tried enabled verbose GPP Printer logging? This might help narrow the problem.

Prudente Sent: Thursday, September 04, 2008 9:57 AM To: gptalk@xxxxxxxxxxxxx Subject: [gptalk] GP Preferences / Vista / Printers / UAC Hi All, For our Vista clients, we have UAC turned off, and users have all necessary rights to install printer drivers from our print server. Users can add printers without any problems either via directly accessing the UNC share, browsing the server, or using the windows printer management web page. Login scripts (vbscript) also will install the printer without any trouble. However, if we use GP Preferences to install certain printers at login, the machine will hang up (seemingly indefinitely) while "applying group policy printer settings." I'm guessing UAC is looking for the OK to install the driver and obviously can't get a response from the user. If the driver is already on the machine, the printer connection will get created as it should, without any delay. If the printer driver were not Vista compatible, users should not be able to install it under any circumstances. Likewise, if UAC settings are wrong, it should balk when attempting to install the driver regardless of the method. Not sure why this would happen. Any thoughts or ideas are appreciated. Thanks, James
