You Cannot Open a File That You Moved to a DFS Share

This article has been archived. It is offered "as is" and will no longer be updated.
You may not be able to open a file on a Distributed File System (DFS) share. This problem may occur in the following scenario:
  • You have a DFS share and a regular share on the same server.
  • You have mapped drive letters to both shares on a client computer.
  • You move a file from the regular share to the DFS share.
  • You try to open the file on the DFS share.
If you look in the Shared Folders snap-in, you see that there is still an open handle with write access to the file. The handle is not released when you log off the client.
This problem occurs because a handle that is supposed to be cleaned up asynchronously is not cleaned up.
