I have to bind my IIS website to port 443. No other port is allowed in my case. In IIS Manager I've bound Default Web Site to port 443:
But when I try to start the website it fails with:
netstat -anob shows nothing to be listening on port 443. TCPView from SysInternals and Windows Resource Monitor both agree with netstat.
How can I find out what is listening on port 443 and stop it so I can run my website on 443?
I'm using IIS 8.5 on Windows Server 2012 R2.
Update on 30 Mar. 2016 It turns out that I could use a port other than 443 after all. So starting the website is no longer a problem for me. Sorry for wasting everyone's time; there was a communication error. But I'll leave this question open in case anyone else faces a similar problem. It might still be useful to know how to find out what's blocking IIS from starting on a particular port when netstat shows nothing is listening on that port.
