I started having issues with the WSUS console (2012 R2).  It would throw an error but if I click reset server node, then it is ok.  I narrowed it down to a computer group.  When I clicked on the group, it would error out.  I cleared the MMC cache and when I click on the group, it is ok.  However, the default view is 'failed or needed'.  When I change the view in this group to 'any' then it fails again.  It only happens with this one group. I get the same error when trying to view from powershell.  Database is SQL 2012 express.  I have a couple workarounds I could try but wanted to get some opinions first from some SQL experts as to how to troubleshoot since this is a weak area for me.
