[Samba] Copying Files

[TJ Davis]

For some reason when I try to copy some files from a windows machine to a
samba share on a particular Linux server it creates the filename on the
share and then gives me the following error:

This folder already contains a file named "foo.exe"

Would you like to replace the existing file which is 0 bytes
with this one which is 13.4mb

It does not do this with all files.  I copied two different iso files that
are approximately 650mb fine several times but I have tried with exe files
and some work while some do not.
