Exchange 2003 NNTP Server Policy

The following table lists the services that must be enabled to support NNTP (the Exchange 2003 NNTP.inf file configures these settings automatically). This security policy is applied only on an Exchange back-end server because NNTP is not deployed in the same manner as HTTP, POP3, and IMAP4, where a front-end protocol handler proxies requests to the back-end data store. In this context, NNTP is a "back-end" only protocol; therefore, for front-end servers, you should not enable NNTP in accordance with the settings in this table.
