Error 720 no ppp control protocols configured

[Hardik]

One of my brothers computer which is 10 months old is running Vista Business and service pack 1 is also installed. He is using Norton Internet Security and a dial up connection. So two days before he was doing a live update with his antivirus and as it was going to finish he received and error message and telling him to restart his machine. So he restarted his machine and when he went back online to finish his update he got another message and he was not able to connect: error 720 no ppp control protocols configured. I have done many research to solve this issue but cannot find any solution for it? So if anyone can help us out, it would be great. Thank you

I will tell you why this problem occurs, you have set the VPI and VCI which is invalid, so please check the VPI and VCI values from your Router, if you unknow the value VPI and VCI. Please contact your ISP service for this.

When you attempt to connect to a Remote Access Service (RAS) server by using the TCP/IP protocol, you may receive the following error message:
Error 720: No PPP control protocols configured.

To resolve this issue, follow these steps:
1. Find out which protocols the RAS server is running, and make sure that the RAS service is installed and configured properly (or ask the Network Administrator to do this).

2. After you find out which protocols the RAS server is running, make sure that your Windows XP-based computer is running one of the same protocols that the RAS server is running:
a. Click Start, click Control Panel, and then double-click Network Connections.
b. Under Virtual Private Network, right-click the VPN connection, and then click Properties.
c. In the VPN Connection Properties dialog box, click the Networking tab, and make sure that you have a protocol that the RAS server is running.

3. If you do not have a protocol that the RAS server is running, add the needed protocol:
a. Click Install, click Protocol, and then click Add.
b. Click the protocol that you need to install, and then click OK.
c. Click Close in the VPN Connection Properties dialog box.

If by any means you have enabled Netbeui, then it will act as the default protocol, uncheck this protocol and then make sure you have tcpip enabled on the dial up connection.
