shell vs subprocess
The problem is the default option "Shell" is "False" , you you write commands 
you should turn on the shell.
for example try this to show the content of directory " C:\Python26
":
>>>import subprocess
>>> p = subprocess.Popen("dir", shell=True,stdout=subprocess.PIPE, 
>>> stderr=subprocess.PIPE)
>>> stdout,stderr=p.communicate()
>>> print stderr # if errors doe not occur ,it is empty!

>>> print stdout
