Live Communications Server 2005 with SP1 improves on the features of Live Communications Server 2005 by extending the federation model, enhancing functionality, increasing security, and improving performance and infrastructure support. These improvements include:

  • Tools to enable Public IM Connectivity; the ability to add contacts, send instant messages, and share presence information with users of the three main public IM service providers MSN, AOL and Yahoo!.
  • Enhanced federation, which uses DNS-SRV resolution to simplify connecting to federation partners.
  • Spam filters for better control of unsolicited instant messages.
  • Support Microsoft Office Communicator 2005.
  • Support for multiple tree Active Directory forests.
  • Improved server API performance.

You can get specific information about this update in the Microsoft Knowledge Base article (897690): Description of Live Communications Server 2005 Service Pack 1.

Live Communications Server 2005 with SP1 is available in two editions: Enterprise Edition and Standard Edition.

Live Communications Server 2005 with SP1 Enterprise Edition Trial Version
Downloadable file name: LCS2005_EE_SP1_Eval.exe.

Consists of a pool of servers connected to a separate, shared SQL Server database that supports over 120,000 users. This two-tier architecture, delivers substantial improvements in availability, scalability, and performance than the Standard Edition.

Live Communications Server 2005 with SP1 Standard Edition Trial Version
Downloadable file name: LCS2005_SE_SP1_Eval.exe.

Consists of single, stand alone IM and presence server together on the same computer with an MSDE (Microsoft Desktop Engine) database for storing user data. It supports up to 15,000 concurrent users and is the appropriate choice in small deployments where enterprise-level capacity, availability and performance are not required.

  • This trial software is intended for evaluation purposes only.
  • When the 120-day evaluation period expires, you can either acquire Live Communications Server 2005 with SP1 or remove the evaluation copy.
  • There is no product support for this trial. You are welcome to participate in a Microsoft Office Live Communications Server public newsgroup to share your trial experiences with others and to ask for advice.
  • Public IM Connectivity requires a per-user; per-month subscription license that is in addition to the Live Communication Server Client Access License (CAL). No trial or evaluation is available for the public IM connectivity service. However, customers have the option of purchasing a small number of public IM connectivity licenses allowing their company to try the service, and then increase the number of licensed users once they find the service meets their needs.
