Description
Provides a scalable, enterprise platform for presence
awareness and instant messaging based on SIP protocol.
LCS 2005 comes in two configurations, Standard Edition
and Enterprise edition. Both editions require Microsoft
Active Directory. The Standard Edition is primarily for
small businesses and the Enterprise Edition is deployed
mainly in medium to large organizations. Both editions are
supported by Microsoft–Polycom solution.
• LCS Standard Edition supports up to 15,000
simultaneous users and provides a stand-alone
presence engine and IM server, which both run on a
single Windows 2003 Server. MSDE provides the user
information database.
• LCS Enterprise Edition can consist of two or more
LCS Enterprise Edition servers connected to a
separate, shared SQL server database.
Active Directory directory service is used by the Live
Communications Server to manage the identities and
relationships that make up network environments. It
includes the user object that allows a unified user name to
be used across multiple home servers. In addition, Active
Directory acts as the central authority for network security.
Office Communicator and Windows Messenger enable
instant communication with co-workers all around the
world from your computer using text chat, voice and video
communication. Office Communicator and Windows
Messenger gives you control over who you talk to, and
when, by letting you view the status of buddies, and add
new buddies to your contact list.
