Unable to Change Home Page Setting in Internet Properties

Q195161

The best way to accomplish this is through group policy (if you have an active directory domain) or through local group policy. To open the local group policy on a machine, Start>Run> and type mmc and hit enter, under the "Console" menu item, click add/remove snap-in, click add and then find the Group Policy snap-in. The snap-in will default to the local machine, accept this and close all the dialog boxes. Under the User configuration in the left hand panel find Windows componenets and under that highlight the Internet Explorer Maint. One of the items in the right hand pane will allow you to set the homepage (I'm doning this from memory and I don't remember exactly what it is called... Important URL's maybe???).

Use Group ploicy if you have AD installed other wise use local group policy.

To open the local group policy on a machine, Start>Run> and type mmc and hit enter, under the "Console" menu item, click add/remove snap-in, click add and then find the Group Policy snap-in.

Under User Configuration > Windows Settings > Internet explorer maintenance > URLs.

On the right side you can see important URLS..Open that and you can specify the home page.
