Can’t start IIS with a binding on port 443?

In case it helps someone:

Getting Event 15005 when trying to start IIS (Internet Information Server) on your machine? In other words, you see this in Event Viewer (eventwvr.msc) under “System”: Unable to bind to the underlying transport for [::]:443. The IP Listen-Only list may contain a reference to an interface which may not exist on this machine.

Troubleshoot using:

netstat -aon | find ":443"

which gives you the process ID in the last column.

Find the process with that ID by using Process Explorer (sort on PID column), then shut down that process.

For me it was Skype (using [::]:443, whatever that notation means – yes, I’m a noob at that notation and can’t be bothered to learn / look it up at the moment)
