But why is the check still running against the AD-host I've disabled? It looks like its that exact dns-check that takes 450 seconds to run (timeout). Looking at the DNS-statistics:
DNS tests executed 4602546.200466 450.096498
which is the normal checks + the 450 second timeout. All other dns-checks run fine.
Shouldnt I except something like this (from the conn checks):
"System unreachable for 764 poll periods (363317 seconds)"
instead of:
"Service dns on xxx07 is OK
Dialup host/service, or test depends on another failed test
Host appears to be down
Timeout
Seconds: 450.003"
when I've disabled all the checks on the host, and the server is powered down? Or am I missing something here?
