I followed your instructions on how to install Apache and they worked fine. The server started without problem. Then I installed PHP and restarted Apache. It gave the “Requested Operation Failed” error. Any ideas? Thanks for the work you did.
A ‘Requested Operation Failed’ error from Apache generally means something is wrong with the configuration file – httpd.conf. It may also result because another program is using port 80.
Firstly, make sure that you’ve edited the Apache httpd.conf file properly. Any stray characters will completely ruin the server configuration and prevent it from starting, resulting in a Requested Operation Filed error. Check and double-check the modifications you’ve made to the configuration file. I also suggest rebooting your computer.
Remember you can test the Apache configuration through “Programs” -> “Apache HTTP Server 2.2” -> “Configure Apache Server” -> “Test Configuration“. If things are fine, a terminal window should quickly appear and then disappear.
The “Requested Operation Failed ” error may also be because of another program using port 80. A case in point is the popular video conferencing program, Skype. To get around this problem, change the port that Skype uses – “Tools” -> “Options” -> “Advanced” -> “Connection” and uncheck “Use port 80 and 443 as alternatives for incoming connections“.
Firewalls and anti-virus programs (Norton) can also be prevent Apache web server from starting up properly.
Conclusion: It seems you have made a mistake while editing the Apache httpd.conf file because of which the web server throws a ‘Requested Operation Failed’ error; remember, it worked fine the first time and failed after PHP was installed.
