We've been using Windows 7 for a while now on an Active Directory domain network. For a reason or another about 2 or 3 times à day all of a sudden, Windows 7 pro is getting very slow to access the network, most of the time when it is trying to browse throught the integrated DFS disk. But also for browsing the network.
Besides, the users can lose their connection with the DFS disk. Than without any warning the connection is back.
All DC and DFS servers are running Windows 2008 R2
We don't have this problem with Windows XP.
