Are the latest four Microsoft security patches not installing for you?  Is KB917537 one of the fixes? Well, it seems that this patch will not install unless you shut down the IIS Admin service and its dependent services manually (thanks Microsoft!).  My suggestion is to uncheck this patch from the list of four new security fixes and install the other three first.  Reboot if necessary after they have installed. Stop the IIS Admin Service and all its dependent services. Install KB917537 and reboot.  Now you’re all set!
