I have searched for answers on this but so far haven't found anything which seemed pertinent. We are moving our redirected folders from Server 2003 to Server 2008. The users which have converted to the new server now get a message stating "[path/file] is already in use. Please try again later" when trying to save Office documents; more specifically it happens when they attempt a second save after saving it once.
Everything was set up the same on both servers - the folder permissions, share permissions, and caching settings. When we move the users redirects back to the 2003 server they can once again save their files.
This migration HAS to happen; am I missing some crucial difference between 2003 and 2008? Is there some extra component of the File Services role I need?
Edit - I have now noticed another symptom. When I go under "Manage Open Files" on the 2008 server I am seeing as many as 4 instances of the file being opened by the same user, plus the temporary file (~filename.xlsx). Hopefully this helps with an idea of what's happening.
