When Windows 2000 clients connect to a Windows 2000-based server using Remote Access Service (RAS) connections, they may receive the following error message:
Error 913: A Remote Access Client attempted to connect over a port that was reserved for Routers only.
Windows NT 4.0 clients may receive the following error message:
Error 629: The data link was terminated by the remote machine.
Windows 98 clients may receive the following error message:
Error 645: Dial-Up Networking could not complete the connection to the server. Check your configuration and try the connection again.
In addition, the following event is generated in the system log of the RAS server, where username is the user name of the connecting user, and port is the RAS port number of the connection port:
Event ID: 20188 Source: RemoteAccess Description: The user username, attempting to connect on port, was disconnected because of the following reason: A Remote Access Client attempted to connect over a port that was reserved for Routers only.
This behavior occurs because the server's RAS port is not configured to accept remote access connections.
To resolve this problem, use the following steps:
Start the Routing and Remote Access administrative tool.
Expand the options under your RAS server's name.
Click Ports, and then click Properties on the Action menu.
Click the appropriate port (L2TP, Modem, PPTP, LPT1, and so on), and then click Configure.
Click to select the Remote access connections (inbound only) check box, and then click OK.
Click Apply, and then click OK.
Microsoft has confirmed this to be a problem in Microsoft Windows 2000.
