Thanks!

Firstly, the script that Im trying to code is written for Windows using the win-32.

The reason why I'm trying to do this is because, the machines to which Im trying to copy files to are under the DMZ. I am an admin for that machine, but want to access it remotely using scripts from my local machine.

I can have only one port open for the purpose, and hence, Im trying to figure out a method.

FTP and other File Transfer methods are not possible due to restrictions implied by the firewall.
Thanks again.
