Daylight Savings Time - Fix for Windows 2000 Servers

In order to get started, download the tool to your Windows 2000 server from Microsoft from the following link: http://download.microsoft.com/download/5/8/a/58a208b7-7dc7-4bc7-8357-28e29cdac52f/TZEDIT.exe

After downloading, run the file, and extract the tzedit program somewhere on your server (The default of Program Files\TZedit is usually fine)

Run the extracted program - by default, the current timezone is already highlighted for you, so go ahead and click "Edit"

Now, enter the new date settings in DST portion of the timezone:
Starts 2nd Sunday of March at 2:00 AM
Ends 1st Sunday of November at 2:00 AM

That should be the only change you need to make - Click "OK", then "Close".

In order to make the server re-read the zone file - you will need to do one of two things:
Reboot the server or Double-click the clock to pull up time and date settings, and under the Time Zone tab, pick a different timezone and hit Apply, and then re-select your real timezone and hit apply again.

You're done! Your server has been updated with the new DST rules, and will change its clock at the appropriate date. More >>>
