Microsoft Exchange 2000 Chat Service, a self-contained component
of Microsoft Exchange 2000 Server, provides a multiuser chat system
where people convene for conversations on channels. One chat server
can host a few users in a department, or up to 20,000 concurrent
users throughout an organization or around the world. Exchange Chat
Service offers superior scalability, reliability, security, and
Internet Relay Chat (IRC) is a protocol that supports real-time
conversation between two or more users over a TCP/IP network. IRC
was written by Jarkko Oikarinen in Finland in 1988 and has since
been used in over 60 countries. By using IRC, people can meet on
channels (also called chat rooms or virtual places) to talk
in groups or privately about specific topics.
A channel, also called a chat room, is a place where group
conversations occur. Channels are dynamic, meaning that anyone can
create a new channel, and that a channel disappears when the last
person on it leaves. In most cases, when a user joins a channel
(enters a chat room), the user can read or hear anything that is
typed or spoken to the members of the channel. More...
A user class is created by an Exchange system
administrator to impose restrictions on a group of chat users.
These restrictions affect the ability of each class member to log
on to a chat community, to create or join dynamic channels, or to
become a channel owner or host. A class can also regulate the
processing of messages from class members and limit the number of
channels members can create in a chat community. More...
Extended IRC (IRCX) is a set of extensions
developed by Microsoft that enhances the functionality of the IRC
protocol and adds several new commands that you can use to manage
users and channels on a chat server. More...
A system operator (sysop) and an administrator
both perform administrative roles for a chat community. An Exchange
system administrator can use the chat community's Security
tab to grant administrator or sysop privileges to a user. Both a
sysop and an administrator can monitor and control a chat
community's channels from a chat client. An administrator, however,
can use administrative commands that are not available to a
Generally, the system administrator of the
client organization determines which chat client software to use.
Considerations for choosing the appropriate client software can
include available disk space, required memory, and ease of
You can configure a user ban for an individual
or a group. You define one user ban for each chat community, so a
user banned from one chat community may be able to access another
community on your system. More...
