|Service Pack 1 Availability|
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.
Federation 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.
Live 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.
While 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:
Search for contacts easily using the new Live Communications Server Address Book Service. This allows users to search for others via their corporate global address list (GAL), as well as local address information on their computer.
Integrate with Microsoft Office Outlook and Microsoft Exchange Server to let users view other contacts' free/busy information from their schedule, as well as display their 'Out of Office' messages directly in Microsoft Office Communicator 2005.
Extend presence, including the ability to allow users to set 'custom notes', to provide more rich information to other contacts, enabling them to make more informed decisions on how to interact. This information is displayed whether or not a user is on or offline, using the offline presence capabilities of Live Communications Server 2005.
Control enterprise phones directly from a PC. With the appropriate private branch exchange (PBX) or public switched telephone network (PSTN) gateway infrastructure in place, Microsoft Office Communicator 2005 provides integration with enterprise telephony systems, allowing the user to initiate calls and even divert calls to a remote location when they are not at their desk.
Initiate conference calls with partner service providers directly from Microsoft Office Communicator 2005 making it easier for information workers to communicate with others.
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.
See the Microsoft Office Communicator 2005 Overview for more information.
Additional improvements to Live Communications Server 2005 SP1 include:
Support for multiple-tree forest topologies previously documented in Knowledge Base article KB#889327. (The article title is An Active Directory forest with multiple trees does not appear as expected in the Live Communications Server 2005 MMC snap-in.) For customers who have an Active Directory infrastructure consisting of two or more root domains that also define independent tree structures and separate DNS namespaces, the Live Communications Server 2005 Microsoft Management Console (MMC) snap-in would not recognize the presence of more than one tree in an Active Directory forest. Live Communications Server 2005 SP1 fixes this previously documented issue.
Improved server application program interface (API) performance. The server APIs in Live Communications Server 2005 SP1 can handle approximately three times more messages with a significantly lower CPU on the server.
Improved in-place upgrade experience. The upgrade process from Live Communications Server 2005 to Live Communications Server 2005 SP1 is via an in-place upgrade that does not require the manual exporting and importing of existing databases as previously required with a Live Communications Server 2003 to Live Communications Server 2005 migration.
Live Communications Server 2005 customers can download the SP1 upgrade for free from the Microsoft Download Center. Volume License customers can obtain a Live Communications Server 2005 SP1 CD by ordering a Microsoft Licensing Fulfillment (MLF) disc kit.
New customers can obtain Live Communications Server 2005 with integrated SP1 that includes all the base server components and SP1 enhancements. The Live Communications Server 2005 with integrated SP1 CD will be available for Volume License customers in June 2005.
120-day Trial Software
A separate 120-day trial version of Live Communications Server 2005 with integrated SP1 is available for download and orderable on CD.
Live Communications Server 2005 SP1 requires a fully installed and configured Live Communications Server 2005 environment.
Public IM Connectivity requires a fully installed and licensed version of Live Communications Server 2005 with SP1.
To enable some of the feature enhancements of Live Communications Server 2005 SP1 new attributes to the Microsoft Windows Active Directory schema are required. For detailed system requirements, please see the technical documentation located at the Live Communications Server deployment center.
