host shows down but it is not

I configured a host with check_mk and it is monitoring 13 services.
All of the 13 services are OK.  The host shows as down however and
I can find no reason for it.  I spoke with Mathias Kettner author
of check_mk and he claims that it is not check_mk that is the
problem.  I configured a host in Nagios (without check_mk) and it
works fine.  I don't understand what is wrong or where to look for
the problem.  Any tips.
