Just a quick update on the DST issue, I've tweaked the MSI I put together so that it can no longer be uninstalled. This is because the MSI overwrites the timezone values in the registry and uninstalling the patch was causing timezones to disappear.
There is no problem with the MSI if you don't uninstall it so I've created a v1.1 that does not allow uninstall.
The patch has been tested on Windows 2000 but not on Windows NT4. I will test on NT4 this week and post a blog article if it works.
The v1.1 patch is available here
