Prelude (skip to solution)
Suddenly by seemingly no fault of my own I was unable to start Apache through the xampp control panel. I decided to investigate this further and ran apache_start.bat in cmd. This gave me the following output:
Diese Eingabeforderung nicht waehrend des Running beenden
Bitte erst bei einem gewollten Shutdown schliessen
Please close this command only for Shutdown
Apache 2 is starting …
(OS 10013)An attempt was made to access a socket in a way forbidden by its access permissions. : make_sock: c
ould not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
Apache konnte nicht gestartet werden
Apache could not be started
Press any key to continue . . .
Ok, so what exactly does this mean? It seems that Apache got some issues binding to port 80. Fair enough, let’s figure out what executable that’s listening to our dear port. I opened cmd and ran the command netstat -ao -p tcp. The very first line said the following:
Proto Local Address Foreign Address State PID
TCP 0.0.0.0:80 Kjetil-PC:0 LISTENING 4
Right, a process ID 4 is blocking our port. Checked it in task manager and the process with id 4 is System. We simply can’t close the process because that would kill the computer session..
Appearently a service called MsDepSvc (Web Deployment Agent Service) can trigger System to listen on port 80. Stop or close the service to solve the problem!
