I am currently an administrator for a government agency. We recently purchased two computers that came with Windows 7, my organization uses static IP address to each machine. We have two gateways on the system, one accesses the internet and the other access a private network that connects through a T1 line. The IP for one gateway is 192.168.1.1 while the other IP address is 192.168.1.120. Windows XP was able to decifer between which packets went to the private IP and which went to the internet, Windows 7 does not do that, it will send an internet web address to the private network and stop, it will not send it to the internet gateway... Anyone have any ides... I already installed the RIP in windows features. The PC's themselves have two NIC's one disabled and the other is functioning. The internet does work work, if you remove the private gateway it has no connection issues.

For the operating system to determine where to send the packets to will depend on the local routing table. Maybe you haven't added the appropriate routes in your table, or are you depending on RIP information provided by the gateways? Either way, the local routing tables need to be updated accordingly. The Windows IP configuration should only have one default gateway configured and have routes defined for that private network.Visit: anITKB.com, an IT Knowledge Base.

What is the subnet for the other, internal, network? I'd leave your interface's default gateway as 192.168.1.1 so it can get to the outside world if all else fails and add a static route to use 192.168.1.120 for your other internal subnets. - Jason
