NT 4.0 Ras error 1066

I installed RAS on my NT server for dail-in only (TCPIP & NETBEUI). However I’m gettin a error in my event viewer saying..
The Remote Access Server service terminated with service-specific error 1066.

The Remote Access Service is not configuredto receive calls, or all ports configured for receiving calls are in use by other applications.

Any suggestions. Thank you.
