Unable to use dail-up networking

I have just replaced my motherboard and processor and
reinstalled windows as it wasnt booting. However, it
doesnt seem to have installed dial-up networking. When I
try and configure a new connection, the options for using
a dial-up are greyed out. Remote Access auto Connection
manager is also not working. I have tried to reinstall
windows again, and have also installed all the optional
components that I could find on the windows disk, but I
cant find anywhere where it gives me the option to repair
Dial-up networking. Can anyone help please? Its driving
me mad!
