Small story a had to move all my network folders to other server alot in the past...
So now im using DFS of my network share \\domain.com\server\share.
I can see all the folders fine put when i try to see the properties of any folders it take maybe 5-10 sec to open the same if I need to launch file .exe file ...
Info : dfs server windows 2008 R2
