[users@httpd] What is Apache not Starting

[Varuna Seneviratna]

I am new to apache I installed apache2.2.8 using the windows installer But
it does not start.I was adviced by help and support of Microsoft to type sc
query and the serveice name and see what the message is and this is what I
got :
SERVICE_NAME: Apache2.2
        TYPE               : 10  WIN32_OWN_PROCESS
        STATE              : 1  STOPPED
                                (NOT_STOPPABLE,NOT_PAUSABLE,IGNORES_SHUTDOWN
        WIN32_EXIT_CODE    : 1066       (0x42a)
        SERVICE_EXIT_CODE  : 1  (0x1)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0

What does this means. What do I have to do
