Daylight Savings Time Changes Updates For Microsoft CRM 3.0

The federal government of the United States changed the start and end dates for Daylight Savings Time, effective in 2007. These changes impact every software application that uses the date and time in any way, and that includes not only Microsoft CRM, but the entire technology stack that it sits on (Windows Server, IIS, SQL Server, Exchange Server). Microsoft has released updates for all of these programs to adjust them for the new Daylight Savings Time, which goes into effect on March 11, 2007.

The place to get started is here: Microsoft Dynamics CRM 3.0 Time Zone Data Updates (KB 925874) and Microsoft Dynamics CRM 3.0 Update Time Zones Wizard (KB 932984). On this page you can download a file called CRM_DST_Remediation_details_Rev1.0.exe which is a 28-page (yikes!) Word document that is in a self-extracting file. This Word document details the steps you should follow to update the entire infrastructure and then the steps required to update Microsoft CRM. The juicy part starts on page 9 of the document, with a step-by-step how-to on updating CRM.
