Live Communications Server 2005 Service Pack 1 OverviewUpdated: October 31, 2005
Live Communications Server 2005 Service Pack 1 (SP1) enables you to take advantage of updates and improvements to Live Communications Server 2005. On This PagePublic IM Connectivity (Licenses Sold Separately)Live Communications Server 2005 SP1 delivers the tools necessary to connect customers to public instant messaging (IM) Internet service providers (MSN, AOL, and Yahoo!). Using Microsoft Office Communicator 2005, Live Communications Server 2005 enabled users who are licensed for public IM connectivity, can now add contacts, send instant messages, and share presence information with users of MSN Messenger, AOL Instant Messenger (AIM) and Yahoo! Messenger. Live Communications Server 2005 Service Pack 1 offers administrators controls (for example, which users connect to which public IM service providers). Where appropriate, administrators can choose to log messages sent to and from the public IM service providers. While Live Communications Server 2005 SP1 is freely available for existing Live Communications Server customers, Public IM Connectivity licenses are sold separately. See the Live Communications Server 2005 Public IM Connectivity Overview for more information. Enhanced FederationFederation is the ability to establish trusted relationships between your organization and one or more external organizations allowing users to initiate and share IM sessions and subscribe to user presence across network boundaries. Live Communications Server 2005 SP1 simplifies the deployment model for the federation feature delivered in Live Communications Server 2005 by making the discovery of Live Communications Server environments (or Access Proxies) dynamic, no longer requiring static configuration. SP1 also gives network administrators the ability to limit enhanced federation for their organizations to explicitly designated external domains (the recommended configuration), or extend it to any and all external domains. The enhanced federation of Live Communications Server 2005 SP1 uses Domain Name System Service Location (DNS SRV) resolution to locate the Live Communications Server Access Proxy of a federated organization. This enhancement, therefore, eliminates the need to specify the Access Proxy of each and every federated organization and provides the Full Qualified Domain Name (FQDN) of your organization's Access Proxy to these organizations. While simplifying the process, Live Communications Server 2005 SP1 uses mutual Transport Layer Security (TLS) to secure the federated connections. Live Communications Server 2005 SP1 offers additional administrative control over the number of incoming and outgoing connections created on an individual Access Proxy. With SP1, customers can support an increased number of Access Proxies in a single array, offering additional capacity for more federated connections. Enhanced Security and Spam Over IM ControlLive Communications Server 2005 SP1 introduces two new filters to help protect your organization, and each enterprise-to-enterprise federated connection, from malicious attacks. The first is an optional spam over IM (SPIM) filter that reduces unauthorized or unsolicited messages and is configurable to suit the needs of your organization. Instant messaging and sharing presence information with users connected to public IM Internet service providers (MSN, AOL, and Yahoo!) are restricted to names explicitly specified in each user's Allow or Block list. This restriction provides additional control of unsolicited messages, or SPIM. A new IM filter application blocks messages that contain URLs or attempt to initiate a file transfer. This application can be enabled when there is an effort to propagate a virus in your organization through these methods. Support for Microsoft Office Communicator 2005While Live Communications Server 2005 SP1 supports Microsoft Windows Messenger 5.1 for basic presence and IM scenarios, SP1 delivers support for Microsoft Office Communicator 2005. New client features supported by Live Communications Server include:
With Live Communications Server 2005 SP1 and partner solutions for telephony integration, Microsoft Office Communicator supports enterprise telephony integration, including call control, call intercept, and presence-enabled call forwarding as well as easy-to-initiate public switched telephone network (PSTN) conference calling and Microsoft Office Live Meeting sessions.
