User group policy not updating
For home users, the default is Enabled, meaning home users get a UAC dialog box.However, for domain users this UAC is disabled so that installation can proceed silently.What I received was this error message: 'The requested operation requires elevation'.Fortunately, the solution was easy; as you can see from the screen shot to the right, just right-click the Command Prompt and select Run as administrator from the shortcut menu.
User Account Control: Detect application installations and prompt for elevation.
The purpose of this page is to explain how to disable the UAC, Vista's nagging 'Continue' pop-up dialog box.
For security, whenever you need to configure Vista settings, you need elevated privileges - even if you are logged on as the administrator.
In the case of Vista Machines which are not joined to a domain, Microsoft provide a menu in the Control Panel whereby you can turn UAC off. In this instance your decision is this: does the security risk outweigh the irritation of having to click 'Continue' every time you wish to perform an administrative task?
My problem occurred when I wanted to run the command: ipconfig /release.
