Execute batch script on remote computer

[py]

I am trying to execute a batch script on a remote computer.

The batch script looks like:

@echo off
start c:\python24\python.exe c:\a_script.py


Here's the setup:
Computer A (my computer), Computer B (the remote computer).

So I map "W:" to Computer B and then copy the batch script to Computer
B.  Then from within Python on Computer A I run:
import subprocess
subprocess.Popen("W:\\foo.bat")

However, when it runs it says it can't find c:\a_script.py.  It seems
to be trying to look
at Computer A, not Computer B.  How can I do this?

Thanks
