(Intro: I have worked with computers since the IBM 7090, but primarily in application development. I owned a small business computer support company for a number of years, so networking and setup issues rubbed of on me, but I don't consider myself to be and "expert".)
I recently set up a HP Desktop computer with Windows 7 on and Windows Server 2008 network.
I have set up several other similar computers on Windows networks.
The primary user, who has been given Administrator privileges, doesn't seem to have administrative privileges.
For example: if she tries to install or update an application, she is told that she does not have proper privileges.
What stones should I look under to find the problem?
