Updated: Feb 21, 2026

Technical Meaning

The ERROR_NETNAME_DELETED error code indicates that a network name, such as a NetBIOS or DNS name, has been deleted or is no longer available. This can occur when the network name was explicitly removed by an administrator or due to changes in the network configuration.

Error Details

This error typically arises from operations involving network names, such as file sharing, network discovery, or remote access. The specific context of the operation determines whether this error is encountered, and it can be returned by various Windows API functions that interact with network resources.

Usage Context

The ERROR_NETNAME_DELETED error code is commonly associated with operations involving network names in the Windows environment. It may appear when attempting to access a network resource using a name that no longer exists or has been removed from the system's network configuration.

Developer Interpretation

When encountering this error, developers should consider several factors:

  • Network Configuration: Ensure that the network name being used is still valid and not deleted. Verify the network settings on both the client and server sides to ensure consistency.
  • API Functionality: Understand the specific API function that returned this error. Different functions may have different behaviors or requirements for network names, so consult the relevant documentation for precise details.
  • Error Handling: Implement appropriate error handling mechanisms in your code to manage situations where a network name is no longer available. This can include retrying the operation with updated network information or providing alternative methods of accessing the resource.
