Ahh, yeah I guess that makes sense. I don't use them either, except for 
a few service dependencies. We have an i5 AS400 here where the services 
that we're checking are dependent on a login service. If you can't 
login, you can't check the services, but that doesn't mean that the 
other services are down.

This is the only time I've ever needed to use host/service dependencies. 
I guess there are specific applications for the need of them. :)
