something is blocking the ports or your routing is not correct. Please check that windows firewall/antivirus/any firewall is correctly configured. It may also have something to do with the type of network topography you are using. Subnets and more exotic network configurations are also difficult so forward and route.
If after you have checked your firewalls and anti virus, and its still not working, could you give us a little more information on your internet connection, including routers, modems......
