In this section we will briefly cover the use of these tools to monitor a DNS server environment. Testing DNS Server Configuration with the DNS Console Monitoring Tab The DNS console provides a simple but effective tool for ensuring that the DNS service is working properly. To use this tool click the Monitoring tab of the properties for the DNS server as shown in Figure . Figure Performing Simple and Recursive Queries Using the Monitoring Tab of the DNS Server Properties The Monitoring tab allows you to perform a simple and a recursive query test to ensure proper operation. A simple query test uses the DNS client installed on the DNS server to send a local query to the DNS server. A recursive query test uses the local DNS client as well. However in this case the DNS client requests that the DNS service use recursion to resolve an NS-type query for the root zone. Failure of this test usually indicates a problem with network connectivity or incorrectly configured root hints. In the example in Figure the recursive query test failed because the network adapter was unplugged before the test was run and the DNS server could not connect to the servers listed in the root hints file. When a DNS server fails one of these tests a warning symbol is displayed on the DNS server in the DNS console. Note that you can set up automatic simple and recursive query testing in the Monitoring tab. It is a good practice to use these tests after you have set up a DNS server or have made a configuration change on a current DNS server.
