DST
Is there a video that I can watch before reading all the KBs: Yes there is. Click here to start watching.
What are the steps involved in using the DST tool?
- Apply the Windows OS patch. This makes the computer aware of the changes in DST schedule.
- Run the rebase tool. This adjusts existing appointments to comply with the DST changes.
- Apply the Exchange patch. This ensures succeeding appointments are DST-aware when booked.
Applying Windows patches
Where do I find the patches? For XP, 2003 and Vista, They are found here. For Windows 2000, registry keys need to be copy/pasted. Details are found here.
What if Vista SP1 is being used. If SP1-Beta is being used, uninstall SP1 and apply SP1-RTM found starting here.
What if there is an issue with the installation of the patches? This is a hotfix issue. Log a support incident classified as a Windows update issue (NOT an Exchange/DST issue).
Running the rebase tool
What if the Exchange patch has been applied before using the rebase tool? DST adjustments will not take effect. Exchange patch needs to be uninstalled and rebasing repeated.
Do I really need to use the rebase tool? No. Calendar items can be manually updated using the “How to manually update calendar items” section of this article.
What should I check before running the tool? Go through the “What to do before you run the Exchange tool” section of this article.
What if there is error running the rebase tool? Using the Find option of your browser, this KB contains most of the error codes associated with the DST tools.
Error codes not found in the KB
Is the SystemPatchDate parameter being used? Re-run the tool without the parameter because there is a bug.
What if the tool is still generating an error? Log a support incident classified as an Exchange/DST issue.
Applying the Exchange patch.
Where do I find the Exchange patches? For 2003, they are found here. For Exchange 2000, an Extended Hotfix Agreement is required.
