Il y a a peu de différent ways to do it. Do you want to force everyone's home page, et disallow changes? Or do you juste want to set a par défaut home page that people can modify?
If you want to force a home page: (Do what HopelessN00b said)
Créez un nouveau GPO ou edit le existing one. (Je suis assuming you know how to do this already. Let me know si you don't.)
In le Group Policy Management Editor, allez dans User Configuration -> Policies -> Administrative Templates -> Windows Components -> Internet Explorer.
Find le policy Disable changing home page settings.
Set it to Enabled, et specify le URL for votre home page.
Once it applies, le option in IE will be greyed out on le client PC.
If you want to specify a par défaut that people can change:
My preferred method would be to use Group Policy Preferences to définissez le nécessaire Registry values. (Others may disagree.)
In le Group Policy Management Editor, allez dans User Configuration -> Preferences -> Windows Settings -> Registry.
Right click -> New -> Registry Item
Action = Update
Hive = HKEY_CURRENT_USER
Key Path = Software\Microsoft\Internet Explorer\Main
Value Name = Start Page
Value Type = REG_SZ
Value Data = votre Home Page URL
On le Common Tab, check Apply Once et Do pas Re-Apply
Cela va définissez le home page par défaut for everyone, mais le user will be free to edit it afterwards.
If you go this route, I aussi recommend that you set a value for Default_Page_URL as well, without checking Apply Once et Do pas Re-Apply. Cela va give votre users le ability to click le Use Default button in le IE settings et get back to le company home page.
You probably aussi want to supprimez le Secondary Start Pages et Default_Secondary_Page_URL registry values as well.
If you are unfamiliar avec these registry values, it would probably be a good idea to ouvrez le Registry Editor et look at HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main to understand how they work.
Other ways you can définissez le IE home page:
One thing to note about GPOs: Any of le settings in le "Preferences" sections of votre GPO will seulement apply si you have le Group Policy Preference Client Side Extensions et le corresponding dependencies installed. Windows 7-era PCs support this out of le box. Cependant, Vista et XP machines need an update to provide this functionality. A fully updated machine should déjà have this installed, mais si do a reinstall it will take a peu de patch-reboot cycles.
