    There is nothing you could do on F5 to solve your problem.

     

    Here are the options you have:

     

    1) Configure Windows DNS to track failed requests. If failed requests counter crosses certain threshold, stop sending DNS requests to that F5 DNS node, send all requests to the other F5 node and generate a Alert that one of the F5 DNS node is down.

     

    2) If Windows DNS is not smart enough to do health monitoring, make it smart. For example, write a power-shell script to regularly check F5 DNS service availability

     

    Hope this helps,
