Internet Information Service not installed

Got bit by this on my personal servers in the past week.  A very helpful post pointed me to the issue: 

SharePoint 2013 CU August 2013 – “Internet Information Services not installed”

Except…mine was a tad bit different.  The IISADMIN service was completed removed from the WFE!  This was due to a SharePoint Server windows update not completing and failing.  In order to get it back, I simply re-ran the pre-req installer and once the service came back, I was able to load the Central Admin and continue with windows updates.
