Error 720: Unable to connect to internet


    I am trying to help out a friend. She has a Dell Dimension 2400, Service Tag 2VG3341 running Win XP Home with Service Pack 2.

At startup we get a message from Norton A/Virus 2003 - Symantec cannot scan your email address, because your network is not properly configured.

Canceling this message and trying to connect to the internet using the Dial –up connection gives this message:

Error 720: A connection to the remote computer could not be established. You might need to change the network settings for this connection.

I have checked the Network Properties as per Windows Troubleshooter, but cannot find anything unusual.

I have also ran the Dell Diagnostic CD, but these tests have are all clear.

The Windows firewall is also disabled

When I try to enable it I get the error message –

Windows Firewall settings cannot be displayed because the associated service is not running. Do you want to start the Windows Firewall Internet Connection Sharing (ICS) service?

After clicking on “Yes”

A dialog box shows “Starting the Windows ICS

Then comes the message “Windows cannot start the Windows Firewall /ICS Services”

Do you have any suggestions?

Try running the utility from the following link on the system in question:


Download and Save the utility on a flash drive, then transfer it to the faulty system and run it.

All the best.
