In release 1.2.3i5 the Check DNS option in WATO has been cleaned up. It is only meant for really checking DNS servers, not the local resolver of a system. If you like to test the local name resolving on a specific host, you can deploy the agent plugin "resolve_hostname" on the host you like to run the check on. The name to be resolved needs to be changed in the first lines of this plugin.
