home server

hi, i am interested in setting up an internet server at home. ive read a fair few documents on the internet about how set one up but i still dont really understand what programs to use, and how they work. ive downloaded apache2.0 because i was told to but i dont know how to work it. can anyone give me some help like a link to a site that will take me through the whole process step by step.
thanks
kevin

This looks like a good guide to get you started:

Before you go spending lots of money, or put lots of work in, make sure that your ISP is OK about it, many of them would take a dim view of you running your own webserver.
