damn random mishaps....internet doesn't work

[Peegee]

This isn't on my computer (it doesn't even have an OS installed), but it is the computer at home. I ran ad-aware and it probably erased a system file (though I don't think it did....though it probably was the cause of dad's and now this computer).

I rebooted to find that internet doesn't work. I tried running ping, and go the following:

'unable to initialize sockets interface. Error code 0'

what's going on? I've reinstalled windows twice with no change. I have no idea how to install TCP/IP or whatever could be the problem (I've tried installing all the windows installation programs in the control panel)...

I will be gone for the next two days, and will have little time when I return. If this is solvable please leave a detailed explanation. Thanks k bye *wave*

edit: it's windows ME....
