Technical Meaning

The error code ERROR_DS_NAME_ERROR_TRUST_REFERRAL with the numeric value 8583 and hexadecimal representation 0x2187 indicates a failure in resolving a name within an Active Directory environment. Specifically, this error occurs when the resolution process encounters a situation where a referral to another forest is required but cannot be completed successfully.

Error Details

This error typically arises during operations involving trust relationships between forests in an Active Directory domain. When a request for a resource or user name involves a cross-forest operation and requires a referral, the system attempts to resolve this referral. If the resolution process fails, this error is returned.

Usage Context

The context in which this error might occur includes operations such as:

  • User logon attempts involving trust relationships between forests.
  • Accessing resources or objects that are located in a different forest within an Active Directory domain.
  • Administrative tasks requiring cross-forest resolution of names or identities.

Developer Interpretation

Developers should interpret this error code to indicate that the name resolution process has encountered a situation where it needs to refer to another forest for further resolution. This typically means that the initial request cannot be fully resolved within the current domain, and additional steps are required to complete the operation successfully.
