    there are three options below it. 1. Keep Blocking 2. Unblock 3. Ask

      HI arno ,

      In the firewall setting i have unblocked this program and tried. But
      it works on some machines on the LAN and doesnt work on other
      machines.
      Even if the firewall is on it work on some machines. So narrowing down
      on the problem seems tough here....

      any ideas?

          As mentioned before, try:
          * Turning _off_ _all_ _firewalls_.

          cheers

              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)
