If you have installed or re-installed Apache server and you are facing error corresponding to port 80 specially when you think of yourself completely insane during installation, it is very possible that some other service is accessing Port 80. Following is the error message which appears while starting Apache as service or running httpd command from command prompt within Apache bin directory –
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

Apache Lounge (The Apache Webmasters & Programmers Community) is quite useful community to look out for resolution of most of your Apache related doubts, specially on Windows platform. The solution to above problem can be found at this thread. There is another useful thread which details about problems faced while re-installing Apache guiding about un-installation procedure and then installation of apache and PHP along-with their consolidation. I faced this problem after the consolidation, so came across this thread too.
