- This issue may occur if TCP port 80 is grabbed by a different service.have
- Possibly occurs when you just enable windows feature IIS for the first time in your PC.
- Eg: If you have installed skype before turning IIS, skype takes port:80.
- Try running below command in cmd prompt to see which process is using port 80.
- netstat -aon | find “:80”
- If your skype is running, close it and start the IIS. When you restart skype, it picks other port.
