i:\xampp\apache\bin>httpd -k install
[Sun Apr 15 07:12:30 2012] [error] Apache2.2: Service is already installed.
i:\xampp\apache\bin>httpd -k start
i:\xampp\apache\bin>httpd -k shutdown
The Apache2.2 service is not started.
Apache does not started and leave no messages on command prompt and "apache\logs" folder.
At this case how to find any clue to resolve this problem?
Any comment would be appreciated.
Thanks in advance.
