For connections using Secure Sockets Layer (SSL), the port number associated with the SNEWS
service is used; for all other connections, the port number associated with
the NNTP service is used.
To change the port number used by the server, edit the Services file and change the port number associated with these services. The default port numbers for the SNEWS and NNTP services are 563 and 119, respectively.
You can also force the Internet News Service to connect to a specific port
number you when make an outbound connection for a news feed. This is useful
when traversing a firewall that can map port numbers to different
destination hosts on the Internet. To specify the port number for outbound
connections, you need to edit the registry.
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that you can solve
problems that result from using Registry Editor incorrectly. Use Registry Editor at your own
risk.
To specify the port number for outbound connections:
- Create the news feed.
- Create the following REG_DWORD registry value, and set it to a value between 1 and 65535:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeINS
\Parameters\Newsfeeds\Newsfeed Test\PortNumber
The
Newsfeed Test registry value should be replaced with the name of the
news feed you want to customize. If this registry value exists, it overrides
the value in the Services file for any outbound NNTP connections for that
news feed. It does not affect the port number used for accepting inbound
NNTP connections. That is always obtained from the Services file.
If you plan to specify a custom NNTP port, you may not be able to download
the active newsgroup list from your news provider with the Newsfeed
Configuration Wizard because the registry value does not exist at that
point. Instead, you should import it from a file or download the active
file after you have set the registry value.
