Error 733: the PPP control protocol for this network protocol is not available on the server.
1) Ensure that the TCP/IP protocol is installed on your RAS server and that the TCP/IP protocol is selected in the Server Settings of the Network Configuration option of the Remote Access Setup dialog.
2) If you have the "Use DHCP to assign remote TCP/IP client addresses" option selected for the TCP/IP protocol in the RAS Server Settings, then ensure that you have installed DHCP and that it is not disabled.
3) Ensure that all of the bindings for TCP/IP are enabled in the Bindings tab of the Network dialog of the Control Panel. Be sure to inspect the TCP/IP Protocol and WINS Client (TCP/IP) bindings for all adapters, all protocols, and all services. If the TCP/IP bindings are corrupt, you may have to reinstall TCP/IP and or RAS in order to clean up the bindings.
