Microsoft Live Communication Server (LCS)

Microsoft Office Live Communications Server 2003 is a manageable and extensible instant messaging server (IMS) that provides a real-time collaboration solution. It enables corporations to reach, collaborate, and respond to information more quickly as compared to telephones and e-mail. It uses the following protocols:


  • SIP (Session Initiation Protocol)
  • SIMPLE (Instant Messaging and Presence Leveraging Extensions) and
  • RTP (Real-Time Transport Protocol).

Windows Messenger 5.0 is the only client application that is used with Live Communications Server (LCS).

This article doesn’t explain the configuration of the IM Archiving feature and provides only some high level steps to configure LCS. This article is based on Windows 2003 Enterprise Edition (Build 3790) and Microsoft Live Communication Server 2003

Introduction

On a home server, Live Communications Server is configured to host users who communicate in real-time and to run Live Communications applications. You must configure at least one server in the environment as a home server. To configure a home server, the computer must be a member of an Active Directory domain.

You configure Live Communication Server on a front end server because a front end server can reduce the load on LCS home servers by redirecting initial registration requests from clients to their assigned home servers. The front-end server redirects the client to its correct home server. The client now contacts its home server for all subsequent traffic. A front-end server must be a member of an Active Directory domain.

Live Communications IM Archiving Agent

The Live Communications IM Archiving Agent component allows you to save IM messages in an MSDE or MS SQL database. The IM Archiving feature collects instant message data and sends it through Microsoft Message Queuing (MSMQ) to a computer that runs Live Communications IM Archiving Service. You must install Live Communications IM Archiving Service on a computer in the same domain before you install the Live Communications IM Archiving Agent component.
