View source for MS Office slow to open files on DFS shares

== Overview ==

The other day a user reported that her Excel files opened very slow.  The files were mapped to a drive letter, but the UNC path for that mapped drive was on a DFS Namespace.
After a little googling I came across a blog post that discussed the same issue.<br>

Recap: The cause of the problem is a simple permissions issue. If the user does not have the 'Read Permissions' right on every level of the DFS path then a series of access denied events take place, but eventually access to the file is granted because the user has explicit rights to the non-DFS share.

Its a simple solution really,  all you need to do is make sure users have 'Read Permissions' on every step of the DFS path.
