Getting tired of dealing with this issue. If you tempt to drag and drop
a file via normal windows explorer from for example a local drive to a
folder on the network, it will always tell you that the destination file
is in use.

I have to use XP with VMware on my machine in order to overwrite files.

Also I am still seeing issues where just visiting a folder locks files
in it and I have to clear the connections at the server.
The server is already set with

SET client file caching enabled=off
SET level 2 oplocks enabled=off
