Watchdog not checking DNS properly

[cmaxwell]

For some reason Watchdog is not checking the status of our DNS server properly. The DNS server is running fine and under Service Management is is showing as running, but Watchdog seems to think it is down. Is there any way to fix this? Is there a file that Watchdog uses for the configuration of the DNS service?

We're running Plesk 8.2.1 on CentOS 4.5 and BIND 9.2.4.

Thanks.
