We have 2 sites – our Forest root runs is Win2003 in Site1, and win2008 in Site2. When we implement a certain policy it only takes effect when we do gpupdate/force and took about several restarts, sometimes we need to delete the profile and create another, and worse we do reinstallation. This is wierd and i could not understand why it usually happens in our win7 machines mostly in Site2. We dont have any issues with XP machines. I have read several KB but still to no avail. Have anyone experienced this one and appreciate if you could share how have it resolved?
