KISS SYSTEM= Keep It Simple Stupid. You need somthing like server software to handle that. I use a Nat box and a switch but if you do not have one of those you need somthing like Winproxy Software. Silly XP sould have Winproxy built in but I bet there is not some similar program inside. Winproxy is a pain to run that is why i eventually built a Nat box. It's a small computer running Linux acting as a server tht works extremly well. Switch is the best way I'd say. I like it better that a hub it is trickier to use till you figure it out. Different operating systems is where WinProxy can be a real pain but the server machine will be running that software. Now what you can do is plunk WinProxy on a useless not to slow Win box (Yard sale stuff) and keep it as that server then just plug everything into the switch. That box only does the server nothing else. I own this software but I never use it anymore. I wonder if I can sell it. It's a older version though. There is different softwares around too. I'm not saying this is the best or cheapest but it worked for me when I used it till I built the NAT firewall box. Now XP should be able to do this of course but it's probibly some stupid option that costs way to much extra. I wouldn't trust XP to be a server anyway. It's a hole in one..... All operating systems are just DOS"s Disk Operating Systems. There only job is putting / finding files on the drives and now days TCP/IP and of cource letting you see it on the screen. That it. The rest is BLOAT. The part you use of XP that's atually the DOS is less than 10 megs the rest if you deleted it carfully would not even be missed. The computer would still work just find and be 500% faster. Even though computers are fast there still serial devices and not parallel so the more instructions you have running in the background the slower you puter goes. FAST= WIN 98 Lite on a 3 gig computer SLOW= XP on a 3 gig computer So explain to me what is so good about it? I'm not a XP expert so maybe somebody else knows how to get the proxy server on it running properly if it's possible. If I had to upgrade my operating system right now cause WIN98 lite no longer worked I'd use WIN2000 If the box had to remain assimilated otherwise I'd just use Linux and delete Winderbugs.
