When was the last time you ran the SBS 2008 BPA on your servers or your clients servers? There are regular updates to the rules used in the SBS 2008 BPA that mean you should consider running it on a monthly basis to ensure that all things are working well. I ran it tonight on my production SBS 2008 box and found a few new items that I was not aware of. The screen below is a summary of the things wrong on my server right now.
It only took me 30 minutes to resolve most of them – I’ve elected to leave the Exchange Server 2007 Service Pack 2 installation for now as I’ve just applied Exchange 2007 UR10 which I want to test for a few days to ensure there are no issues with it. Aside from that I’ve gone through and rectified a number of other items and it’s now much cleaner (not perfect, but cleaner). Put a diary note in for end of next month to do it again.
