>how can I correct this alert?
Fix your DNS.
This non-fatal error is Apache's way of telling you that it can't work out the hostname of the machine it's running on.
It uses reverse DNS to determine this information. If you don't have a reverse DNS entry for your server's IP address, this is what you get.
Fix your DNS and the alert will go away, or just ignore it.
