USAGE: Dfsutil /PurgeMupCache is a special problem repair command that should only be executed on the client.   The MUP cache keeps information about both DFS and other shares on the client system. Suppose, you create a non-DFS (e.g SMB) share and access it before mapping a DFS namespace by the same name on it.  The MUP cache might still think that the share is served by the previous provider (SMB) although DFS is the correct provider now.  This command clears the MUP cache so there won't be any confusion  about the current provider when such names conflict.   Usage: dfsutil /PurgeMupCache     This command does not take any arguments.     e.g: dfsutil /PurgeMupCache  Notes: 1) Except for a temporary performance hit, this command has no other adverse effects.  2) This command does not affect any DFS metadata on disk. 3) If this command isn't executed and the namespace isn't accessed, the obsolete cache entry will eventually expire anyway.
