Internet Explorer Maintenance Group Policies do not apply during subsequent logons procedures

You configure Internet Explorer on Windows 2000-based client computers by using the Active Directory Internet Explorer Maintenance Group Policies to customize the Internet Explorer Home page.

The policy is applied only the first time that the user logs on. The user's home page is changed to the home page that is specified in the Group Policy Object (GPO). If the user later changes their home page to a different page, the GPO never sets it back to the page that the user specified in the GPO during a subsequent logon procedure.

This behavior is applicable to all Internet Explorer Maintenance Policies.

Note: This article is not applicable if you are running Internet Explorer Maintenance Policies in Preference mode.

During subsequent logon procedures, Gpt.ini is queried and the version is checked. The client believes that the GPO has already been applied and therefore the IEAK\Install.ins file is not requested during the second logon procedure. Because the Install.ins file is not requested, the Home_Page value is not processed and is not reset to the home page that is specified in the GPO.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
To resolve this behavior, the client must always apply the policy even when there are no changes to the GPO in case the user has changed their home page to something other than what is specified in the GPO. To make these changes:

NOTE: You must change this registry value on the client, not on the domain controller. You can also resolve this issue by setting the "Internet Explorer Maintenance Policy Processing" policy under Computer Configuration\Administrative Templates\System\Group Policy.

1. Run Regedt32.exe: Click Start, click Run, type regedt32, and then click OK.
2. Navigate to the following key in the registry:
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions\{A2E30F80-D7DE-11D2-BBDE-00C04F86AE3B}
3. Change the NoGPOListChanges value by changing the value from 1 to 0.
   
   By default, this value is set to 1. When you set this value to 0, the client refreshes the policy even when there have been no changes to the GPO during subsequent logons.
