Updated: Feb 21, 2026

Technical Meaning

The error code DNS_ERROR_NODE_IS_DNAME is returned when a DNS query or operation encounters a node that is identified as a DNAME record. A DNAME record is used to map a domain name to another domain name, which can be used for aliasing purposes in the DNS system.

Error Details

This error code indicates that the operation attempted on a specific DNS node was not appropriate given its nature as a DNAME record. For example, operations such as creating or modifying A records directly under a DNAME node would result in this error because DNAME nodes are used to redirect queries and cannot contain other resource records.

Usage Context

This error is typically encountered when performing DNS-related operations through the Windows API or related tools that interact with the DNS service. It can be returned by functions such as DnsQuery or DnsUpdateRecord, among others, depending on the specific operation being performed.

Developer Interpretation

When this error code is received, it signifies that the operation attempted was not valid for a DNAME node. Developers should ensure that operations are appropriate for the type of DNS record they are working with. For instance, when dealing with DNAME records, developers should focus on operations related to redirection or aliasing rather than direct resource record management.
