Dell OMSA - won't run after installation of KB3161608

I recently installed the latest batch (June 2016) of MS updates on our servers.  It went well except for two servers, a PE2950 and a PE2970, both running Server 2008R2.  These are our only two servers running Server 2008R2.  On both machines, after installing all the updates, I was unable to open OMSA.  The browser would display 'Internet Explorer cannot display the webpage'.  OMSA continued to work fine on the rest of our servers, most of which are running server 2008.

I tried a different browser, but that didn't work.  OMSA was at 7.3, so I downloaded and installed 7.4.0 and the 7.4.0.2 update.  I found references to similar problems online, and some of the fixes included installing OMSA using the command prompt, or 'runas admin'.  I installed them every which way, but no matter how I installed it, I got the same result!

I didn't find any errors in the server's event logs. 

So I started uninstalling updates until I found the one that broke it, and it was KB3161608.  Uninstalling that update fixed OMSA on both servers. 

This updates is listed as optional, so I'm not sweating it for the time being.  I believe it's a certificate problem, and might be fixed by creating a new self-signed certificate for those servers, but this isn't really my area of expertise.  But I wanted to put this out there, in case it might help someone else.
