I'll try to be online in the evening, I just logged in for a few minutes today.
Try enabling the IPX protocol and playing through it.
What you're quoting sets the priority for the adapter; if the server is visible in the server list, it won't help.
Configure everything on the main network, and if that doesn't work, feel free to contact me on ICQ. I'm very tired right now, and my brain isn't working, so write to me in the evening.

P.S. Do you have a shared network? If the game can see it, there should be one...
