I've added two Windows 7 laptops to a Windows SBS 2003 Domain but keep getting pop-up windows when installing new programs/ making changes asking for the Domain Administrator credentials. I know them, so I can enter them and proceed, but I can't seem to figure out how to give the PC/ user sufficient privileges to avoid these messages. I know I've done this before, but seem to be having trouble working out what to do this time. I have double-clicked on their user profile in SERVER MANAGEMENT, clicked on the MEMBERS OF tab and have added them to Power Users, etc, groups but there is no change, even after a restart. Please help!
