yeah a million ideas...
really it sounds like a firewall problem, specially cu it work on one  
machine but not on the other.
try switch it off completely... obviously "unblocking" doesn't seem to  
do the job

if it works on one machine, the code is obviously ok
i assume you;re on a windows machine?

to mention some other possible reasons,
are you using an IP or DNS name?
maybe the firewall blocks the DNS server and can't retrieve an IP for  
the server?
can you access the internet from those machines?

maybe the machine is not on the same subnet as the server
can you ping the server?

for more reasons i'm afraid you have to try another list
since this doesn't sound like a python problem
and i'm definitely not a windows guru (only osx, linux and freebsd here)
