Strange IO Error when extracting zips to a network location

I've written a script to run on windows to extract all zips under a
given directory path to another directory path as such:
python extractzips.py <fetch all zips under this dir> <put all extracted
files under this dir>
The purpose of this script is to retrieve backup files which are
individually zipped under a backup directory tree on a backup server.
This scripts works nicely and has input validation etc, exiting
gracefully and telling you if you gave a non existent start or target
When running the script as follows
python extractzips.py \\backupserver\backupshare\machine\folder d:\unziphere
the script works perfectly, but if I do
python extractzips.py \\backupserver\backupshare\machine\folder
then it unzips a lot of files, recreating the directory tree as it goes
but eventually fails with the traceback:
File "extractzips.py", line 41, in zipextract
IOError: [Errno 22] Invalid argument
But I'm sure the code is correct and the argument is passed properly,
otherwise a hundred files before it wouldn't have extracted successfully
using this exact same piece of code (it loops over it). It always fails
on this same file every time. When I extract the same tree to my local
drive it works fine without error.
I have no idea why pushing to a network share causes an IO Error,
shouldn't it be the same as extracting locally from our perspective?
It pulls fine, why doesn't it push fine?
Thanks for any help or suggestions anybody can give me.
