Problem connecting two simultaneous networks TCP/IP - NWLink IPX/SPX

[animateme]

Hello,

I am trying to setup two separate network connections, using two separate network cards, on a Windows XP computer. One connection will be for a TCP/IP Windows based network (with internet access) and the other will be for a NWLink IPX/SPX/NetBIOS, (DOS based) Novell type network.

I have installed both NICs but the problem I am having is that when both networks are connected at the same time, the TCP/IP Windows based network connects fine but the NWLink IPX/SPX network does not connect. However, if I unplug the cable of the TCP/IP Windows based network, then the NWLink IPX/SPX network connects fine.

I assume that the TCP/IP Windows connection is causing some kind of conflict somehow with the other connection and that is why it is not allowing it to connect.

I have tried disabling the NWLink IPX/SPX/NetBIOS protocol in the Connection Properties for the TCP/IP Windows connection and have also tried changing the Network Connection Bindings but it does not make any difference.

Would there be anything that I can try to troubleshoot where the issue is? Any help will be greatly appreciated.

Thank you.

Dis you put each Network on its own subnet?

Thank you for your reply. Both connections are set to "obtain ip address automatically" so no specific subnet is defined. Should I try assigning a specific IP, Subnet Mask and Default Gateway? I know that the Windows based network uses the 255.255.255.0 subnet but how can I determine which subnet to use for the other NWLink network?
Thanks.

OK, I tried assigning static IP address for both connections, changing to different subnets on each one, but the issue is still there. I also changed the subnet on the router to match the one assigned on the connection settings.
Anything else I can try? Thank you.

Here are the screen captures for the configurations. As you can see, this is Windows in Spanish but you should be able to figure it out (if not, please let me know and I will translate).

This is the setup for the NWLink IPX/SPX/NetBIOS, (DOS based) Novell type network:

This is the setup for the TCP/IP Windows based network:

Thank you.

It's been forever since I've worked with IPX/SPX. Are the networks on different segments or are both protocols running on the same segment?

I finally solved this by putting both networks on the same hub, connected to a single NIC and using the same subdomain. Go figure... it was that simple!
Thank you all for you help. Greatly appreciated!
