Well the tool was called the SBS Best Practices Analyser (Analyzer for the US guys) but it’s been called the Windows Server Solutions BPA since it was re-released for the SBS 2011 platform.
Microsoft have released an update for this just this week. They announced it here. The BPA works on SBS 2011 Standard Edition, SBS 2011 Essentials, Windows Storage Server 2008 R2 Essentials and Windows MultiPoint Server 2011.
It’s 100% best practice to run this tool over any new installation that we do as well as any new site we inherit as it really helps to see if there are issues that we can solve quickly that Microsoft already know about. Get the update now and check it out.
