Green computing is our featured topic this month, and we start with a great article about Building a Green Datacenter by Dave Ohara. In this article, Dave outlines some important energy related problems and solutions being addressed by IT teams today.

Following on this theme, Jim Lynch writes in our Field Notes column about the benefits of recycling hardware through programs such as the Community Microsoft Authorized Refurbisher (MAR) program.

We also have articles on Active Directory replication, managing updates with System Center Configuration Manager 2007, and how Microsoft uses Exchange Edge Transport servers and Forefront Security for Exchange Server.

For you SQL Server fans, we have some handy tips on optimizing SQL Server CPU performance, and Nancy Michell is back with a new installment of SQL Q&A.

In addition, you'll find all of our regular columns including Security Watch, Windows PowerShell with Don Jones, Hey, Scripting Guy!, The Cable Guy, The Desktop Files, Windows Confidential with Raymond Chen, and more - all available at www.technetmagazine.com.
