You should monitor the DNS: Dynamic Update Received/sec, the DNS: Total Query Received/sec, and the DNS: Total Response Sent/sec counters using the System Monitor.
Key Takeaway: System Monitor can be used to report statistical information about the DNS server. This will help determine if performance on the DNS server is what it should be. The Dynamic Update Received/sec counter displays the total number of dynamic update requests received by the DNS server. The Total Query Received/sec counter displays the average number of queries received by the DNS server every second. The Total Response Sent/sec counter displays the average number of responses sent by the DNS server every second.
