When I'm trying to start the Apache 2.2 server it is showing the following message: **The Requested Operation has failed**

In command Prompt it is showing as follows:

```
C:\Documents and Settings\amth>net start apache2.2
The Apache2.2 service is starting.
The Apache2.2 service could not be started.

A service specific error occurred: 1.

More help is available by typing NET HELPMSG 3547.
