Check system log in Windows 2003 Server

Click Start->Control Panel->Administrative tools -> Event Viewer
There are three logs:
Application, Security and System.
I checked system log and I found that I can not restart Apache2.2 due to following error message:
"The Apache2.2 service terminated with service-specific  error 1 (0x1)"
First check any syntax  error in httpd.conf using:
httpd -t
return "syntax OK".


According to 
http://www.itauthor.com/2007/05/15/if-apache-fails-to-start-after-a-reboot/
The problem may be due to IIS admin using port 443, or other applications using port 80, or httpd.conf pointed to the no-exsitin directory. Another article for reference:
