No Internet after Windows reinstall

[umma]

I reformatted my hard disk and reinstalled Windows XP but now I have no Internet - what can I do to fix it, Internet Explorer works but I can't connect to the Net. I'm posting from my brother's computer, please help me.

Well, all you need to do is call your ISP (Internet Service Provider) - they will guide you trough the process, most likely you will have to create new Internet connection, edit a few settings, and your connection should be up and running in no time.
