Microsoft released recently a couple of Exchange Server 2007 technical whitepapers:
The Microsoft Exchange Server Jetstress Tool v08.02.0060 is available to download:
Simulate disk I/O load on a test server running Exchange to verify the performance and stability of your disk subsystem before putting your server into a production environment.
Use Jetstress to verify the performance and stability of a disk subsystem prior to putting an Exchange server into production. Jetstress helps verify disk performance by simulating Exchange disk Input/Output (I/O) load. Specifically, Jetstress simulates the Exchange database and log file loads produced by a specific number of users. You use Performance Monitor, Event Viewer, and ESEUTIL in conjunction with Jetstress to verify that your disk subsystem meets or exceeds the performance criteria you establish. After a successful completion of the Jetstress Disk Performance and Stress Tests in a non-production environment, you will have ensured that your Exchange disk subsystem is adequately sized (in terms of performance criteria you establish) for the user count and user profiles you have established. It is highly recommended that the Jetstress user read through the tool documentation before using the tool.
Jetstress 2007 (08.02.0060) Updates: Configuration files and databases created with 08.01.0177 release of Jetstress will not work with version 08.02.0060 . A new configuration file and new databases must be created when using the 08.02.0060 release.

The Microsoft Internet Security and Acceleration (ISA) Server 2006 Service Pack 1 was finally released.
Microsoft® Internet Security and Acceleration (ISA) Server 2006 Service Pack 1 introduces new features and functionality to ISA Server 2006 Standard and Enterprise Editions.
The new features focus on configuration change management and enhanced troubleshooting designed to help you identify and resolve ISA Server configuration issues within the ISA Server Management console.
The service pack includes the following new features and feature improvements:
- Configuration Change Tracking—Registers all configuration changes applied to ISA Server to help you assess issues that may occur as a result of these changes.
- Test Button—Tests the consistency of a Web publishing rule between the published server and ISA Server.
- Traffic Simulator—Simulates network traffic in accordance with specified request parameters, such as an internal user and the Web server, providing information about firewall policy rules evaluated for the request.
- Diagnostic Logging Viewer—Now integrated as a tab into the ISA Server Management console, this feature displays detailed events on packet progress and provides information about handling and rule matching.
Improvements for existing features, including:
- Support for integrated NLB mode in all three modes, including unicast, multicast, and multicast with Internet Group Management Protocol (IGMP). Previously, ISA Server integrated NLB-supported unicast mode only.
- Support for use of server certificates containing multiple Subject Alternative Name (SAN) entries. Previously, ISA Server was able to use either only either the subject name (common name) of a server certificate, or the first entry in the SAN list.
- Support for Kerberos Constrained Delegation (KCD) cross-domain authentication. Credentials from users located in a different domain than the ISA Server, but in the same forest, can now be delegated to an internal published Web site by using KCD.
- Support for client certificate authentication in a workgroup deployment. This removes the requirement to map each client certificate to an Active Directory® directory user account when forms-based authentication is used as the primary authentication method and client certificates are used as the secondary method.
For more information about this service pack, see Microsoft Article 943462.
For general information about installing ISA Server updates and hotfixes, see Microsoft Article 885957.
Hey, did you notice that SAN certificates are now fully supported?
