When you try to open a file or document that resides on a Distributed File System (DFS) share, it may take a long amount of time to open the resource (from 90 seconds to 15 minutes). However, you may be able to quickly open the same resource by using a UNC path.


The problem is caused when the WebClient redirector does not cache information.
