I some what agree with these guys. If your going to go the xp route then Pro is the way to go, no questions asked. I still see windows 2k as a valid option it even might be better for a cafe because theres less new tech involved with it. Someone once told me theres cutting edge... then theres bleeding edge. Also what do you want your custemers to be able to do? if its just web surfing then stick them behind a proxy for more controll and firewall all out going ports. Leaving them with no actuall access to the outside world. As far as locking down the machine us gpedit.msc along with a strong administrator pass and restrick there access to a little more then guest access. I guess the best thing to do here is to look at it like this. What would the people be doing on your lan? web surfing/word processing and other sh1t like that. Simple enuff, maybe make sure theres a good printer in there and carge $0.0x per page or something like that. Games are simple maybe a big pipe like some sort of T1 or big dsl package, but isnt the reall fun just being on a lan? Mind you I havent been to an internet cafe in a wile. All I can say is dont pirate your software, the more public your software is there more likly the BSA/IRAA/MPAA are likly to come peeking around. Im not saying that they would... just that they could, so keep stuff on the up and up. I think thats all I got, hope this was helpfull.
