RAS Errors 611 and 720 With PPP or SLIP
Symptoms: When you attempt to dial out from a Windows NT Remote Access
Service (RAS) client using the Remote Access protocol Serial Line Internet
Protocol (SLIP) or Point to Point Protocol (PPP) to a TCP/IP server, one of the
following error messages appears:
Using SLIP
Error 611: Route is not available
Using PPP
Error 720: No PPP control protocols configured.
Cause:
This problem may have several different causes. Two known causes are the
NetBIOS interface not being installed and the NetBIOS binding being
disabled. The NetBIOS interface is required for establishing logical names
and sessions on the network for Windows NT.
Resolution:
To correct this problem, select the Network option from Control Panel and
do the following:
- Verify that the NetBIOS interface is installed.
- Verify that the bindings of the NetBIOS interface are enabled and
properly established with the NDISWAN drivers.
