Unable to start IIS Admin service with HResult 0x80010119

I'm unable to start the IIS admin service, or run IIS Reset. Whenever I do this I get the following error appear in the event log:

The IIS Admin service terminated with service-specific error 2147549465 (0x80010119).

Just kill inetinfo.exe via task manager. You might also need to kill all processes relating to IIS, like iissrv.exe. After that iisreset will work again.

Same problem was described here

If your problem still exists you might need to specify your system details like .NET version, what version of windows / IIS etc.
