We run DFS shares on the file server side and Office 2007 or 2010 on the client side.
Clients access files on the file share through the dfs share, not a direct mapping to a server.
We replicate the dfs share and set only one copy as enabled in dfs management to avoid competing updates and replication conflicts.
When Microsoft Office opens a file (Word or Excell) it creates a Office Owner file that has the same name as the opened file but wit the prefix "~$". If the users closes this file it is supposed to be removed from the share. In our environment this owner file sometimes does not get removed and causes problems when another user wants to open that file and he/she is told the file is read only. Manullay locating the ~$ file and deleteing it solves the issue, but we really want to figure out, why in some cases the `$ file is not deleted when a user closes the document.
