Error 720: No PPP Control Protocols Configured

SYMPTOMS
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.

CAUSE
This behavior can occur if your computer and the RAS server do not have a protocol in common, or if RAS is not configured correctly.

RESOLUTION
To resolve this behavior, 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.
