IIS not working

Had a server where IIS was not serving the websites out consistently, or at all. Trying to restart it via the GUI didn’t work, nor did iisreset. iisreset at least gave an error:

“IIS admin service or a service dependent on IIS Admin is not active.”

Trying to start IIS Admin Service via the service manager wouldn’t start either. I ended up killing inetinfo.exe with the task manager, then running iisreset and the admin service. That worked.
