How to reinstall a system for a LAN server

According to what you said, your friend's machine has been dialed up as soon as you turn it on, which means that you should have a router, right, as for the splitter seems to have no dialing function, right and can not guarantee that the traffic of each machine is the average, right. If you have a router, it should be fine, you want to install any system is fine, if you do not have any special files need to use the server system, then you use the same XP, as for the VIST I am not too optimistic about it, it is too high on the hardware requirements, and a lot of things are not as good as XP. As for some of the settings you just do not go to the router on the line there is also your IP address a An to be configured correctly, must be the same with the router in a network segment ah, line said how much I went to bed, good if you add my points it.
