Thank you both for giving me a few more gray hair this morning. Ive spent the past 3 weeks preparing for the DST change in North America , reading endless knowledgbase articles, patching all my systems and thinking that everything was going to be alright. Wrong. I came in this morning to an email from an external partner saying the MS approved TZEdit program does not work. So all my Windows 2000 servers and workstations will need to be updated, again.
To get Windows 2000 to recognize the changes you make in TZEdit you have to change the timezone you are in to a different one, i.e. from Central to Eastern, apply the change and then change it back again. After doing this you will see the correct time on the clock.
For those of you running XP or Windows 2003 you can apply a registry edit that will fix the problem for you. I've created the file for you here. Save the file to your desktop, then run it accepting all prompts.
