Installing and running the Best Practices Analyzer for your SBS server is strongly recommended. In addition to identifying errors that you need to address, the BPA may also generate a list of warnings that you should review.
You may determine that a particular BPA event is not applicable to your server, and you do not want to keep seeing it. That’s easily handled by clicking on the “Do not show me this item again for all instances” option – which will hide that event when viewing or generating a BPA report.
But, what if you accidentally selected the wrong item to hide? How do you get it back?
Well, the answer is simple, but perhaps not intuitive.
With your BPA report on display, change the “Select Report Type” from “List Reports” to “Other Reports” and, voila, you will see a list of BPA events that you previously selected to not show. Locate the event you wish to unhide and click on the “Show me this item again for all instances” option.
P.S. Please note that there are different versions of the Best Practices Analyzer for SBS 2003, SBS 2008, and SBS 2011.
