IE9 homepage configured by GPO doesn't work

Hi all,

I've configured a customized homepage for IE by GPO.

In my company we're using IE8 in Windows XP machines and IE9 in Windows 7 machines.

While the homepage configured by GPO is applied OK in IE8, the same in IE9 isn't working. However, after I run gpupdate /force, it works.

It's annoying, because every new user who logs in a computer with IE9, doesn't have the customized webpage, we've to connect to their computer and run gpupdate /force for apply the configuration.

My computer, where I made the changes in the GPO, is a Windows 7 machine with IE9 installed, so, I've the new inetres.admx

Any suggestion?
