Task: Service check—simple and recursive resolution Purpose To insure that DNS name resolution is functioning within specifications, periodic testing should be performed. Procedure 1: Simple and recursive test query Using the DNS Manager GUI: 1. Start the DNS Manager from Administrative Tools; or click Start, click Run, in the box, type and then click Run dnsmgmt.msc OK. 2. Select from the console tree the applicable DNS server. 3. On the Action menu, select Properties. 4. the Monitoring tab. 5. Check the Simple Query check box. 6. Test Now. The results may be viewed in the Test Results dialog box. 7. Uncheck the Simple check box and check the Recursive Query check box. 8. Click Test Now. The results are displayed in the Test Results dialog box. Using a command line: 1. Click Start, click Run; in the Run box, type cmd and then click OK. 2. To perform a simple or recursive in the command shell enter: NSLookup <HostName> <DNS Server> A simple query may be initiated by using a Hostname command that makes the DNS server authoritative for the record. A recursive query test would include a Hostname command that makes the DNS server not authoritative for the record. A comprehensive recursive test may also involve a flushing of the name cache to ensure that DNS forwarding is utilized during the recursive test.
