Since I installed the latest BPA on my Western Digital DX 4000 which has Windows Storage Server 2008 R2 Essentials on it, I’ve had the alerting pop up with a Computer Monitoring Error as you can see in the screen shot below. This alert pops up on all the client machines that are connected to the server. I’m not the only one to have seen this however, a number of fellow MVPs have seen this too. Together we’ve figured out that the latest Best Practice Analyzer (BPA) is the culprit and that removing it from the server has “resolved” this issue for the moment. Microsoft are aware of the issue and are investigating it at the moment.
This error also occurs on other servers that use the same Best Practice Analyzer including SBS 2011 Essentials and Windows Storage Server 2008 R2 Essentials.
I’ll report back here once I know of a solution – for now, I suggest that you install the BPA and then after you’ve run it to determine the health of your server and rectified anything that needs to be fixed, remove the BPA.
