A few words of thanks would be greatly appreciated.

Dial up connection failed!

It may happen that your computer failed to connect to the internet if you use direct connection, i.e via telephone line.

The first thing that you should do is that you ensure that your cable is well plugged in both sides.
Ensure that your modem is switched on or well connected on correct port of your computer. For external modem, ensure power is switched on.
Ensure that remote server is functioning properly.
Verify that dial number for your accessed server is well input.
