One of my many roles is that I’m responsible for and manage a number of BlackBerry Enterprise Servers (BES) for both our company and our customers. From 40 user BES Express up to 10,000 user licensed resilient enterprise systems. Some of them I’ve implemented, some I’ve inherited. I know some messaging system administrators don’t really get along with the BlackBerry Administration Service (BAS) that’s been available since version 5, but I quite like it – especially for publishing apps which is *so* much easier!
I really like the PowerShell for Active Directory, that you find in Windows Server 2008 and above. I cut my teeth on PowerShell with Microsoft Exchange Server 2007, and love the ability to script almost everything – even if the script is just a bunch of repeated commands against a list in Excel, that’s copied and pasted.
