When trying to save a modified Excel file, which has been opened from a network share, our users are receiving the following message:
Someone else is working in "\\domain.com\users\username\Document.xls" right now. Please try again later.
The clients that have been affected are Windows 7 clients, and the DFS share is being served from a Windows 2012 server. I have already confirmed that DFS replication has not been enabled, so it isn't trying to lock files for replication. I have also disabled any real-time scanning that is occurring on the client to make sure that the AV software wasn't locking the files. I did notice when viewing the list of Open Files from the server's Computer Management console that when a users experiences this issue the file appears to be opened 4 times. Three times it shows that it was opened in Read mode and the 4th instance shows an Open Mode of Write. Typically, a file which is working correctly should just show one instance with the Open Mode of Read+Write. None of these open instances are temporary files preceded with a ~.
Any thoughts?
