I was having problems when my computer started windows so I did a repair with the Windows XP Pro Disk. After the repair everything seemed fine until I tried to connect via Dial-up to the internet. Everytime I try it says there is no modem configured but if you check modems it is fine and it dials through Hyperterminal. I tried to configure the connection manually but the options for dial-up are grey-out unavailable. I called tech support for my internet provider and they suggested reinstalling dial-up networking but we couldn't find how to do it. So my question to everyone. HOW DO I REINSTALL DIAL-UP NETWORKING. I've tried another repair and also I tried an upgrade installation to my existing Windows XP pro and nothing worked. Also keep in mind I cannot format this machine because of vital data not backed up.
