SBS 2011 and Windows Update Error 800B0001

As we enter 2014, there are still plenty of new SBS 2011 servers being installed in offices. SBS 2011 is the last version of Microsoft’s Small Business Server (SBS) product line. SBS 2011 comes with Exchange, SharePoint and WSUS pre-installed.

If your site also has Windows 8/8.1 computers, you may discover that running Windows Update on those computers may generate an error 800B0001.


Now, if you do your due diligence and search for this error, you will find suggestions that a credential on your Windows 8 computer is corrupt, and that you should run a pair of DISM commands to attempt to repair the situation:


But, in most cases, running these commands will NOT resolve the issue. So what’s causing the error?

Simply put, you are missing a couple of required updates on your SBS 2011 server, updates that resolve the issue of Windows 8/8.1 communicating to the WSUS server:

KB 2720211 – Update for WSUS 3.0 SP2

KB 2734608 – Update for WSUS 3.0 SP2
