We have two machines, both windows 7, both in the same OU with the same GPO settings.
One has the LAN settings (Proxy page) with everything greyed out. The other does not have this greyed out.
Looking at our GPOs, I see nothing that would do this.
User Configuration\Administrative Templates\Windows Components\Internet Explorer\Disable changing proxy settings
Also, just to be sure:
User Configuration\Administrative Templates\Windows Components\Internet Explorer\Internet Control Panel\Disable Connections page
The only difference is one is running SP1, while the other is not. I am updating now to test and see if SP1 somehow does this.
Any other places where this could be greying out the proxy settings?
