networking

What network mask is configure for each system?

What operatin system on each computer.

What type of connectoin are you trying to establish? File sharing? FTP? Web browsing?

Like the previous poster says, we'll need more info. If your IP adresses are not in the same range, you're not going to be able to connect no matter what your OS is; or what kind of connection you want to make. Unless, of course, there are routers installed in your network.

Tip: if using Windows, go to Start>Run and type "cmd"

Then, type "ipconfig /all". Scroll up 'till you see "subnet mask"; which should look like this: 255.x.x.x (replace x with 0 or 255).

Post that subnetmask of both machines and we're making progress... and don't forget to post the info the other poster requested ;)
