Network News Transfer Protocol (NNTP) is an application protocol that is used over TCP/IP networks. NNTP defines a set of client and server commands used to access newsgroups.
Microsoft Exchange 2000 Server uses NNTP to enable Microsoft Outlook users to participate in online discussions over the Internet. Exchange also enables users running client applications that support NNTP to access newsgroup public folders on computers running Exchange.
Users can read and post items, such as messages and documents, to NNTP newsgroups that are represented in Exchange as public folders; for example, scientists can exchange research information by posting messages to a newsgroup public folder for their area of interest. Other scientists around the world can read and respond to items in the newsgroup. Items in newsgroups can be replicated to Usenet host computers through newsfeeds.
Can I have an administrator approve articles before they are posted to a newsgroup?
Why is it necessary to use both NNTP Service and an NNTP virtual server?
NNTP Service in Microsoft Windows 2000 replaces Internet News Service in Exchange Server 5.5. This built-in Windows 2000 service is designed to support a stand-alone newsgroup server, making it easy to create group discussions. When you install Exchange 2000, NNTP Service is enhanced with the capability to interface with other news servers through newsfeeds. NNTP Service communicates with external NNTP servers to make popular USENET groups available to your users.
An NNTP virtual server allows you to administer newsgroup services by controlling authentication and client connections from a centralized location. You can create additional virtual servers to host multiple domains on a single server, or you can create a public and private virtual server and keep them separate for authentication purposes.More...
