Assign an IP Address, TCP Port, and SSL Port

The default virtual server is created with an IP address of (All Unassigned). For instant operation, the NNTP server is identified on the network with the IP address of the computer running Exchange. This allows NNTP Service to receive incoming connections on TCP port 119, and a Secure Sockets Layer (SSL) port of 563 is used. For instant operation, you can use the default IP address, TCP port, and SSL port, or you can assign a different IP address from any available network card; however, if are creating multiple NNTP virtual servers, you must create a unique combination of IP address, TCP port, and SSL port for each server.

Important   Even if you leave the default SSL port set to 563, to fully enable SSL on an NNTP virtual server, you must enable SSL and request and install a certificate.

To assign an IP address, TCP port, and SSL port:

  1. Start System Manager
    On the Start menu, point to Programs, point to Microsoft Exchange, and then click System Manager.
  2. Navigate to NNTP.
