SYMPTOMS
A Windows NT client makes a PPP (point-to-point protocol) RAS (remote access server) connection to a Windows NT RAS server with support for IPX/SPX protocols enabled. A user on a Windows NT RAS client runs a Winsock application that binds to the RAS adapter and listens for connections over SPX or SPXII protocol sequences. Another user on the Windows NT RAS server runs a Winsock application that binds to the RAS adapter on the server and tries to call connect to connect to the application on the RAS client. A call to connect in this scenario fails with SOCKET_ERROR and WSAGetLastError returns WSAENETUNREACH(10051).

RESOLUTION
The RAS server administrator must configure the RAS server so that it assigns different network numbers to all RAS clients. This can be done by clearing the "Assign same network number to all IPX clients" check box. On the Control menu, click Network. Then click RemoteAccessService, click Network, and click IPX.

STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available
