DNS Object
Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2
The Domain Name System (DNS) is an Internet and TCP/IP standard name service. The DNS performance object consists of counters for monitoring various areas of performance of the DNS service, which enables client computers on your network to register and resolve DNS domain names. These names are used to find and access resources offered by other computers on your network or other networks, such as the Internet. The data reported by the DNS object includes the number of overall queries and responses processed by a DNS server, the number of DNS queries and responses processed using either the User Datagram Protocol (UDP) or the Transmission Control Protocol (TCP), the number of queries and responses that used recursion to look up and fully resolve DNS names on behalf of requesting clients, and the number of queries and responses made to servers using the WINS lookup integration features of the DNS service.
