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.
You can control which articles are posted to a
newsgroup by assigning a moderator to the newsgroup. Articles
submitted to a moderated newsgroup are not posted until the
moderator approves them. More...
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.
You can reduce support costs and improve
customer service by giving customers quick and easy access to
technical support information on a public news
server. More...
If newsgroup content is saved in Information
Store, expiration policies set in Information Store cancel any
expiration policies you set on the newsgroups. If you set an
expiration policy for newsgroup content, and a different expiration
policy is set in Information Store for the same content, only the
Information Store policy is used. More...
To create a master server, you use New NNTP
Feed Wizard to define the remote server as a slave. You do not
directly define a server as a master. To define a server as a
master server, you only need to indicate that the server sends
articles to a slave server. More...
Control messages are sent to cancel a posting,
create a new newsgroup, and remove a newsgroup. These messages are
received by NNTP Service and posted to special newsgroups in the
NNTP virtual server's newsgroups listing. The control messages are
posted to one of the appropriate newsgroups: control.cancel,
control.newgroup, and control.rmgroup. These newsgroups are
automatically created to manage control messages. More...
