Point to Point

This depends what you are connecting to. If you have a DHCP or WINS server that you are connecting to then you just enter that info in the TCP/IP setting. But if you are just going through a router then you nees a static address. This address has tobe in the subnetwork that you are trying to connect to if this is going to iternet but if you are just connecting to a server then any address will do but it should be in the range of 172.16.0.0 through 172.16.255.255 for private networks.

Hope it helps

If what you are asking is what it takes to allow two computers on a LAN communicate:

They need a protocol in common. If they are only talking to each other on the same network wire, or attached to the same hub, it does not really matter which protocol.

If you are using tcp/ip, you can assign a static ip to each. A good number range to choose is 192.168.0.x, where x is a number from 1 to 254. Use a mask of 255.255.255.0. All numbers in the range 192.168.n.x are for private networks (non internet). Pick some value, 0 to 254 for n, and use up to 254 stations (the x value).

If you do not want to use tcp/ip at all, you can install NWLINK. Make sure the network numbers are the same on both stations.

Good luck.
