XAMPP Port 80 Issue Ver. 1.8.1

Postby daorner » 12. June 2013 20:47

New install on Vista 32-bit. Removed Skype, no change. Did check with Netstat. Port 80 used by System, PID 4. Suggestions accepted on how to check what services are using Port 80. Also a solution help. I have seen that this is a common issue.

Thanks!

Problem detected!
3:36:23 PM [Apache] Port 80 in use by "system"!
3:36:23 PM [Apache] Apache WILL NOT start without the configured ports free!
3:36:23 PM [Apache] You need to uninstall/disable/reconfigure the blocking application
3:36:23 PM [Apache] or reconfigure Apache to listen on a different port

Microsoft included a proxy service for http communication, http.sys.
This should help that more than one program can listen on the same http port without blocking each other. Badly this doesn't work for programs that don't use this proxy service like Apache.
Thats what it doesn't make easy to solve that issue. Any program can register to that proxy and use it but mainly that are Microsoft products.

common Port 80 or 443 blocking PID 4 programms:
- Internet Information Service (IIS) / World Wide Web Publishing Service (W3SVC)
- WebMatrix / Web Deployment Agent Service (MsDepSvc)
- SQL Server Reporting Services (MSSQLSERVER)

Maybe you can find more information with the following command line commands:
Code: Select all
netsh http show servicestate verbose=yes

netsh http show urlacl
We don't provide any support via personal channels like PM, email, Skype, TeamViewer!
