Verifying Microsoft NNTP Service Availability with Telnet

You can use the Telnet program to verify that Microsoft NNTP Service is accepting connections and responding correctly to NNTP commands. This enables you to determine whether a problem is being caused by the service or by the client.

Before using Telnet, you should verify network connectivity using Ping.

To connect to Microsoft NNTP Service using Telnet:

1. From the Start menu, choose Programs and then Accessories and Telnet.
   
2. From the Terminal menu, choose Preferences, and then select the Local Echo check box.
   
3. From the Connect menu, choose Remote System.
   
4. In the Host Name box, type the DNS name or IP address of Microsoft NNTP Service. In the Port box, type the IP port number being used by Microsoft NNTP Service. (The default is port 119.)

   If the service is accepting connections, you receive a message similar to the following:

   200 NNTP Service Microsoft® Internet Services 5.5 Version: 5.5.1717.0 Posting Allowed

   If you receive a Connect Failed message from Telnet, the service is either not running or not accepting connections. If you receive a 502 Connection Refused message from Microsoft NNTP Service, the service has either paused or reached its connection limit.

5. If the service accepts your connection, type list, and then press ENTER.

   If the service is responding to NNTP commands, it lists the available newsgroups.

   If you receive a 480 Logon Required message, the service is not allowing anonymous access.

6. To end your Telnet session, type quit, and then press ENTER.

If you can connect and run the List command successfully using Telnet, the problem is probably with the client.

If you cannot connect, the problem is probably with the service. Verify the port number and other Microsoft NNTP Service configuration settings.
