Typically, deleting a file across the network will not put the file into any recycle bin, so....
You might want to try something like Recuva from here http://www.piriform.com/recuva/download
Download it from the Piriform link and install it onto the machine that contained the file originally and see if that helps.
There is no way you can undo it. I accidentally deleted an entire partition not long time ago. I used the MiniTool Power Data Recovery and recovered all my files including the very old ones that I intentionally deleted long, long time ago.
