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.
Install a Hotfix, I have given the Microsoft Link for that and create the below mentioned registry key.
Reboot the PC once.
On the Edit menu, point to New, and then click DWORD Value. Type NoSimpleNetIDList, and then press ENTER. On the Edit menu, click Modify. Type 1, and then click OK.
