Those who manage BlackBerry in the enterprise might be interested in some best practices on how to help prevent BlackBerry Enterprise Server downtime from Ahmed Datoo of Zenprise, maybe for your how-to section.

Here they are:

1. Ensure You Have Enough Exchange Server Capacity: Every BlackBerry user added to your environment can generate a significant load on your Exchange server. An Exchange server that is overburdened with users and doesn’t have enough capacity will cause availability problems for BES.
   
   
2. Co-Locate Your BES and Exchange Servers: There is a fair amount of network traffic between your BES and Exchange servers. Co-locating your servers in the same geographic location reduces risk of outages attributed to slow/unavailable network connections.
   
   
3. Consistently Monitor and Audit Your Active Directory Infrastructure: Changes made to permissions within Active Directory can cause users to no longer be able to send/receive e-mails.
   
   
4. Apply Patches on Exchange Server Judiciously as Such Patches Can Break BES: BES server requires the same version of files that can be found on the Exchange server. Patches applied to Exchange that update file versions will cause problems with BlackBerrys.
   
   
5. Monitor Your End-to-End BlackBerry Infrastructure: Set up a monitoring system to detect carrier-related outages or outages with the Research In Motion (RIM) network. This allows you to quickly identify whether the problem is external or within your infrastructure.
