Host Down alert when Host is Up - SOLVED

[Sxan]

Ok, I figured out what was causing this to happen. It
turned out that one of my custom check commands had
the old IP address to use, so when it was not able to
successfully run the check command, it was reporting
the box as being down. I don't know why it would do
that as opposed to just saying the application wasn't
there, but I guess thats how Nagios works. If it goes
to check a service and can't reach the host, a host
down state is assumed. Thanks for the responses as
always.
