What does Windows error code 5010 (ERROR_OBJECT_ALREADY_EXISTS) mean?

ERROR_OBJECT_ALREADY_EXISTS

The object already exists.

ERROR_OBJECT_ALREADY_EXISTS is Win32 error 5010 (0x1392) and belongs to Failover clustering cluster object creation.

Troubleshooting steps

• Record object type, name, GUID, and owner.
• Record create request and idempotency token.
• Record existing object properties.
• Record concurrent management operations.

What to verify

Verify whether a cluster object with the requested identity already exists. Check object type, name, GUID, and owner together with create request and idempotency token.

Handling, retry, and recovery

Read and reconcile the existing object; update it when appropriate instead of issuing another blind create.

Practical example

Automation times out after creating a group and retries.
