G Web Server is slow when using 2 network cards

[nate]

I have an application that uses the CGI functionality of the G-Web Server.  We have recently notices that if we have 2 network cards installed on the PC and both are enabled, the response time of the requested web pages is very slow.  The G-Web Server itself seems to be running normally.  If you disable the extra network card, it responds very quickly.  Any ideas?  I was thinking it might have something to do with the routing table.

How are the two NICs configured? Do they reside on different subnets? Do you use some kind of load balancing?

Yes, the cards are on different subnets. 

I found out just by trying stuff that if you put the client's IP address in the Hosts file of the Host PC (Running G Web Server), it immediately starts responding quickly.  I guess that it has something to do with how Windows resolves network connections.
