DFS Refresh issue in Windows XP SP3

Here I am not going to explain what is DFS, yesterday I have fixed one major issue on DFS. The problem was, File list in the Windows Explorer folder is not refreshed after you create, move, or delete files. AS per Microsoft that issue has been fixed with XP SP2 but I have faced the issue in xp SP3.

Resolution Steps:
Install a Hotfix, I have given the Microsoft Link for that and create the below mentioned registry key.
Reboot the PC once.

Difference between forwarder and Stub zone

Both the zones are used for name resolution but when we are used stub and when we are used forwarder. I am trying to say as small as possible.
Ex: We need a trust between domain A and domain B and am a system admin of domain A and in future any changes happen in domain B, we may not get those update , here best is stub, why? Because stub is automated process and the changes will update automatically.
Forwarder is a manual process. Assume admin of domain B has changed the DNS server but I don’t have the update, here problem comes-up.

If you are aware of the activity of domain B then you can use the forwarder.

N.B: You can not create stub zone and forwarder together with the same zone name.
