Dnscmd Overview

Dnscmd.exe: DNS Server Troubleshooting Tool

This command-line tool assists administrators in Domain Name System (DNS) management.

DNSCmd displays and changes the properties of DNS servers, zones, and resource records. It manually modifies these properties, creates and deletes zones and resource records, and forces replication events between DNS server physical memory and DNS databases and data files. Some operations of this tool work at the DNS server level while others work at the zone level.


  • DNSCmd enhances the functionality of and replaces Dnsstat.exe, a tool included in some versions of the Windows NT Resource Kit.

Corresponding UI

DNS resolves computer names to IP addresses so that users can refer to computers by name rather than by a series of numbers.

For more information about DNS, see "DNS" and "DNS Concepts" in Help for Windows Server 2003.
