Personal Dial-up internet server

Hello, everyone.
I think this is a networking question so it should be ok to post this question
here.

What I want to do:
I want to be able to dial-up my home computer and use its DSL internet
access.

What I have:
PIII 800Mhz PC with 128 meg RAM 120Gig HD DSL Modem 56k Modem.

Do I need some software for this to work, or does windows 2000 have it
all built in? Also, is there a website that has a step-by-step description
of the setup procedure?
Thank you for all the help you can give me.

 

The software is already a part of windows 2000.

You will need a modem in the PC and you should be aware that if you connect to it via dial-up, the best internet speed you get from the remote PC will still be dial-up speed.

Thanks for the info. I am aware that when the remote computer dials up
my computer it will only get dial-up speeds. That is fine.
