Connecting to 2 networks

I'm trying to connect a Win98 machine with 2 NIC to 2 seperate TCP/IP networks one in the for 10.x.x.x and the other on 192.168.x.x. The 10.x.x.x is the machines local network while the 192.168.x.x is a remote connecting via frame relay to a citrix server. When both NIC's are active the machine pronounces the 192.x.x.x network unreachable unless the other netowk card is disabled in which case I get clear access to the remote network.
Could someplease give me an idea of how I can get the machine to operate on both networks if possible.

Thanx

You can only have one IP assigned to a machine at a time. When the machine is assigned an address in the 192 subnet it will be able to access the 192 network. When it is assigned a 10.x IP it will be fine in the 10. subnet. You need routing enabled to be able to access both networks. You can purchase relatively cheap router now a days. You said you have frame relay coming in. Where is that coming from? A switch or router? Try running the 198. line to the router FIRST then from router toyour machine.

With apologies to "User_Deleted" above.. but
You can only have one IP assigned to a machine at a time. When the machine is assigned an address in the 192 subnet it will be able to access the 192 network. When it is assigned a 10.x IP it will be fine in the 10. subnet. is incorrect. You can have multiple IP's. You can even have multiple IP's with a single NIC. See MSKB Article ID: Q156772.

On to the question. Make sure you are not having any hardware conflicts with both NICs enabled. Is the machine getting the IP address via DHCP or are they statically assigned?

Both IP statically assigned without hardware confict. The problem is really that traffic seems to be routed to the 10.x IP by default. I did solve the problem in the end it seems the TCPIP driver files were corrupt and a complete removal of both theNIC drivers and TCPIP protocols on the offending machine solved the problem when a single NIC. Barring the use of RRAS etc I belive there is no way selectively routing btwn 2 subnets. Thanks a lot for you answers the helped a great deal

I agree with answer #2, you can have mulitple IP's on one machine. I would suspect that it is some sort of a problem with DHCP, check your DHCP config.
