The authentication protocol that is used by Microsoft Office Communications Server 2007 and its clients has been updated to require a signature in all messages. This includes the first message that carries the challenge response.
The version number of the protocol that is advertised in the challenge response has increased to version 4. Challenge responses that use version 4 of the protocol must contain a signature. The signature is a digest of the identifying headers in the message. The signature is calculated by using the session key.
Client applications that are built by using the Unified Communications Client API SDK must use this update to register and to work with Communications Server 2007. Communications Server 2007 requires the first challenge response message to contain a signature.

The Microsoft Exchange Server Protocols documentation provides detailed technical specifications for Microsoft proprietary protocols (including extensions to industry-standard or other published protocols) in the Microsoft Exchange Server system.
The Microsoft Exchange Server Protocols documentation provides specifications for protocols that are implemented in the Microsoft Exchange Server system software and that are used to communicate with other products.
The documentation is designed to describe each protocol in detail as it is used by the Microsoft Exchange Server system. Each protocol specification documents the technical requirements, limitations, dependencies, and Microsoft-specific protocol behavior.
The documentation also includes a set of companion overview and reference documents that supplement the technical specifications with conceptual background, overviews of inter-protocol relationships and interactions, and technical reference information, such as common data types and error codes.

With the release of the Scalable Networking Pack that is included with Windows 2003 SP2, we in Exchange support have been seeing some connectivity issues once the new networking features are enabled. These new features are enabled by default and are only used if your network card driver supports them. Some of the new architectural additions that were introduced with the Scalable Networking Pack are TCP Chimney Offload, Receive-side Scaling (RSS) and NetDMA. These were introduced because of the Microsoft Scalable Networking Initiative that was designed to help reduce OS bottlenecks caused by network packet processing. More information regarding the Scalable Networking initiative can be found at www.microsoft.com/snp.
