Hi, recently I've lost the ability to perform a Run as Administrator function on a regular user like installing software. Normally I would get a prompt for an administrator's login info ... now when I right-click and do a Run as Administrator (on a computer with a regular domain user logged in) I don't get the login prompt and the program tries to install and comes up with a statement saying that You do not have sufficient privileges ... contact your administrator. This just recently happened and I haven't changed or added any group policies. Our network consists of Windows 2008 R2 Domain Controllers and the workstations are Windows 7 32/64. Thanks for your assistance.
