My web server was down today. Apparently, the server’s power cord came loose and so it shut down after a couple of hours. After booting it up, I started Apache but it failed. It didn’t display a reason, the process judt wouldn’t start. After googling for ways to view an error log, I found that if you go to apache/bin directory in Command Prompt and run apache.exe -t, either the process will spawn pr you will get an error message. Apparently the problem I was having was that after the reboot, one of my external drives was mapped to a different drive letter than apache was expecting.
