Group Policies applied are not getting updated

I have windows 2000 Domain server & some Windows XP Clients & some Windows 7 Clients.

I modified Group policy to change the wallpaper but the policy is getting applied to some computers only that too they are getting a black background instead of getting the image as wallpaper.

For some clients this is also not coming.Please help in troubleshooting the issue.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing.

Login to one of the client on which the policy has not updated and run GPRESULT & check if the GPO is applied.If yes, run gpudate /force and check if the change has been reflected on the client.

Normally it will take 90Mins to update the GPO changes to client, if you need to take the change immedietally.Then you need to force the client ot update the GPO changes.

Can you run me though steps for disabling desktop wallpaper & fixing a common image to all users as wallpaper.

Users shouldn't have the ability to change the wallpaper by any chance

this is a user configuration in Group Policy.  You can follow the steps here:

If you run into any issues, the client machines may be missing a registry keys that you may need to push out as well.  As first poster had said, can you confirm that the policy was pushed and has been updated?
