Something is clearly wrong. here's *my* XP system connecting to Google:

C:\Steve>python
Python 2.4.1 (#65, Mar 30 2005, 09:13:57) [MSC v.1310 32 bit (Intel)] on 
win32
Type "help", "copyright", "credits" or "license" for more information.
 >>> import urllib
 >>> f = urllib.urlopen('http://www.google.com')
 >>> len(f.read())
2690
 >>>

I suspect you may have a firewall problem: you could need to tell your 
(XP Service Pack 2 personal) firewall it's OK for Python to make 
outbound network connections.
