I've found a problem with pinging pluging

I've created a special config file to add workstations as hosts based on their hostname resolved by the dns server that keeps track of their IP based on the dhcp server ip assignations.

In this file called hosts.cfg I've put this config:

check_command check_ping!200.0,20%!600.0,60%

for check_ping plugin

but in the define host rule
define host {
use generic-pc
host_name myworkstation
alias Windows Workstation
address myworkstation.domain.local
hostgroups pcs
}

From the nagios server command line if I ping myworkstation.domain.local I get response correctly
But from the GUI I see that pinging service fails

But If I put in the address the IP directly, pinging service succeeds.

What might be happening?
