From Microsoft:
In August of 2005 the United States Congress passed the Energy Policy Act, which changes the dates of both the start and end of daylight saving time (DST). When this law goes into effect in 2007, DST will start three weeks earlier (2:00 A.M. on the second Sunday in March) and will end one week later (2:00 A.M. on the first Sunday in November) than what had traditionally occurred.
Depending on the particular product or scenario, these updates will be released through Microsoft Customer Support Services (CSS), Hotfixes incorporated in Knowledge Base articles, Windows Update, Microsoft Update, Windows Server Update Services (WSUS), and the Microsoft Download Center.
Products affected:
Windows Client
Windows Server
Windows Mobile
Windows SharePoint Services
Microsoft Exchange Server
Microsoft Office Outlook
Microsoft Dynamics CRM
Entourage

UPDATE: Here's a list of other blog posts dealing with the DST change issue
I hope the update works this time!

Seems silly to me to spend 9 months of the year on "non-standard" time. Why don't they just call summer time "standard time" and call the winter something like "what daylight? time".
