Operation not allowed on a disabled cross ref.

Updated: Feb 21, 2026

Introduction

This article provides a detailed technical explanation of the Windows error code ERROR_DS_REPLICA_SET_CHANGE_NOT_ALLOWED_ON_DISABLED_CR (0x2193). It covers the context, common causes, and resolution strategies for this specific error.

Technical Background

The ERROR_DS_REPLICA_SET_CHANGE_NOT_ALLOWED_ON_DISABLED_CR is a domain-specific error code related to Active Directory replication. Specifically, it indicates that an operation attempting to change the replica set configuration on a disabled cross-reference (cross-ref) object is not allowed.

Error Details

Numeric Code and Hexadecimal Representation

  • Numeric Code: 8595
  • Hexadecimal Code: 0x2193

Short Description

The error message Operation not allowed on a disabled cross ref. indicates that the operation being attempted is restricted when applied to a disabled cross-reference object.

Common Causes

This error typically occurs due to one of the following reasons:

  • Invalid Parameter Values: The operation was initiated with an invalid parameter, such as attempting to modify a property or attribute on a disabled cross-ref object that does not support such changes.
  • Incorrect Object Type: The operation was performed on an object type other than a cross-reference, leading to the error.
  • Exceeding Limits: There might be limitations imposed by the Active Directory schema or configuration that prevent certain operations from being executed on disabled objects.

Real-World Context

In the context of Active Directory, this error can arise during maintenance tasks such as modifying replica sets, updating cross-reference configurations, or performing administrative actions on disabled objects. It is important to ensure that all operations are performed in accordance with the current state and configuration of the directory service.

Is This Error Critical?

The criticality of this error depends on the specific operation being attempted. If an operation is not allowed due to a disabled cross-ref object, it may indicate a misconfiguration or a need for administrative intervention to correct the state of the affected objects.

How to Diagnose

To diagnose and understand why this error occurs, consider the following steps:

  • Review Operation Context: Ensure that the operation being performed is appropriate for the current state of the cross-ref object. Verify if the object is indeed disabled or if it requires a different type of operation.
  • Validate Parameters: Check all input parameters to ensure they are valid and correctly formatted. For example, verify that the object identifier (DN) provided in the operation matches an existing cross-reference.
  • Confirm Object Types: Ensure that the operations being performed are compatible with the object types involved. Cross-references have specific attributes and behaviors that must be respected.

How to Resolve

To resolve this error, take the following actions:

  • Correct Parameter Usage: Use appropriate parameters for the operation. For example, if modifying a cross-reference, ensure all required attributes are set correctly.
  • Adjust Operation Context: If the object is disabled, consider enabling it or performing operations that do not require active state changes.
  • Restore Data: In cases where data corruption might be an issue, restore from backups or use tools provided by Microsoft to repair Active Directory objects.
  • Retry Operation with Valid Inputs: Attempt the operation again with valid and correctly formatted inputs. Ensure all prerequisites are met before initiating the operation.

Developer Notes

Developers should be aware that this error code is specific to operations involving cross-reference objects in an Active Directory environment. It is crucial to consult the relevant documentation for Active Directory and DSAPI (Directory Services Application Programming Interface) when developing applications that interact with these services.

Related Errors

  • ERROR_DS_OBJECT_NOT_FOUND: This error might occur if the object being referenced does not exist or cannot be located.
  • ERROR_DS_DRA_BAD_SCHEMA_CHANGE: This error can arise if there are issues with schema changes during replication operations.

FAQ

Q: What causes ERROR_DS_REPLICA_SET_CHANGE_NOT_ALLOWED_ON_DISABLED_CR?

A: The error occurs when attempting to change the replica set configuration on a disabled cross-reference object, which is not allowed due to its state.

Q: How can I prevent this error from occurring?

A: Ensure that all operations are performed in accordance with the current state of Active Directory objects. Verify parameters and object types before initiating any operation.

Summary

The ERROR_DS_REPLICA_SET_CHANGE_NOT_ALLOWED_ON_DISABLED_CR (0x2193) is a specific error code related to Active Directory replication, indicating that an operation on a disabled cross-reference object is not allowed. Understanding the context, causes, and resolution strategies can help in effectively managing and troubleshooting issues within the Active Directory environment.
