Daylight Savings and BlackBerry Enterprise Server

An IT Administrator's guide to updating your BlackBerry solution

If you are running BlackBerry Enterprise Server, you need to complete the following steps to accommodate the changes to New Zealand Daylight Savings Time (DST). These steps will resolve the issue for both your BES server and your BlackBerry handsets.

• Update your Windows server and BlackBerry Enterprise Server software. You can download a comprehensive step by step guide, BlackBerry Enterprise Server (BES) NZ DST Preparation guide for IT Administrators. Part of the process in this document requires loading the latest 'cdo.dll' file onto your Exchange and BES Windows servers. Instructions on how to do this can be found here.
• Ensure all your users handsets have been upgraded to at least the software versions shown below, to be compatible with the new DST patch.

You can apply any necessary upgrades with the BlackBerry Desktop Manager. At the same time, you will also need to re-establish the link to your server by re-applying Enterprise Activation. See our guide, How to Upgrade your BlackBerry handset software – BES user for complete instructions.

If you have many BlackBerry users you can create a software configuration on your BES server to push the DST patch out to users automatically. This causes the least impact on users, and is far easier to apply across large teams, especially if they're based in many locations. For this to work the handsets must already be at or above the software levels described above. For more information on this process, see Configuring BES to Wireless Push DST Patch to BlackBerry Handsets - IT Administrators guide.

If you have a smaller number of users, they can download the correct patch from the web via their handset web browser themselves. This is the same process used by BIS solutions.
