Windows 8.1 / Windows 10 breaks my ASP.NET / IIS : “Service unavailable”

With Windows 8.1 finally released to MSDN/Technet today I came across the following issue running my ASP.NET application after doing an in place upgrade with Win 8.1 RTM:

I struggled with similar issues last night.

It started out with a complaint about missing redirect.dll. After installing IIS' Redirect feature, that log message disappeared and all I was left with was a bunch of error messages from WAS. It tried starting my application pool five times until giving up.

A listener channel for protocol 'http' in worker process '120' serving application pool 'my app pool' reported a listener channel failure. The data field contains the error number.

The error code was "8007007E" (File not found according to google).

I then installed ProcMon from sysinternals.com and every time the w3wp process complained about "NAME NOT FOUND" right before terminating, I googled and installed the corresponding IIS feature. I repeated this until I had installed them all and got everything working again.

Installing everything is not a good solution, but I do not have time to investigate deeper right now.
