Imagine my dismay and perplexity today when Apache suddenly stopped working on my development PC. Checking the Windows event log revealed this error:
The Apache service named reported the following error: >>> (OS 10048)Only one usage of each socket address (protocol/network address/port) is normally permitted. : make_sock: could not bind to address 0.0.0.0:80
Aha! Another service is using port 80, preventing Apache from binding to that port. But what? I wondered if I had caught some terrible malware serving out who-knows-what…
However, a quick Google search revealed Skype as the culprit!
