Let's say I have two active network connections that let me out to the internet.

I want certain applications to only use Network Connection 1, while some others should use Network Connection 2.

Is this possible in Windows XP? If so, how can it be done?

What application? I used to do this with browsers simply pointing them to the correct NIC in the Network connections settings. – AdminAlive Nov 23 '09 at 18:44
Needs to be any application. – snicker Nov 23 '09 at 18:49

ForceBindIP - Bind any Windows application to a specific interface (by IP or GUID).

ForceBindIP is a freeware Windows application that will inject itself into another application and alter how certain Windows Sockets calls are made, allowing you to force the other application to use a specific network interface / IP address. This is useful if you are in an environment with multiple interfaces and your application has no such option for binding to a specific interface.

This application would be perfect, except I cannot get it to work even with the programs mentioned as compatible on the page. Firefox just hangs as if it can't find the destination. If I disable the network adapter i don't want to use, it will fall back to the other and work fine, so I know the connection is okay. – snicker Nov 23 '09 at 20:27
i don't use Firefox but it definitely works with uTorrent on my eee pc. – Molly7244 Nov 23 '09 at 22:42
Didn't work for me on my Windows 7 machine with uTorrent application :( – Eran Betzalel May 1 '10 at 15:43
ForceBindIP appears to work on 64bit Windows 7 if you put the DLL into the SYSWOW64 folder instead of the System32 folder. – user38835 Jun 1 '10 at 11:21
ForceBindIP works fine for me on Windows 7 64 bit (after putting the dll in the system32 folder). – Ashutosh Jindal Dec 3 '13 at 19:52
