ODM AD : Failed to register device (4377702)

Devices fail to register during the migration or management process, with error messages similar to the following:

• Error 1:
  Failed to register device (DeviceName: '<DeviceName>', Hostname: '', DomainName: '<DomainName>', DeviceId: '', TenantId: '', AgentVersion: '<AgentVersion>')

• Error 2:
  No objects found for Device: '<DeviceName>' in EndpointId '<EndpointId>'

This issue occurs when the device was previously registered but the endpoint has lost the device's association. This situation requires re-reading the device into the endpoint and reinstalling the agent after removing old registry entries.

Resolution Steps

Step 1: Verify the Device Status

1. Run a Read Workflow in the migration/management tool.
2. Ensure that the device appears under the Not Ready Devices list in the tool.

Step 2: Uninstall the Existing Agent

1. Delete the existing agent registry entries:
   • Navigate to the following location in the Registry Editor Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432NODE\Quest\On Demand For Active Directory\ODMAD_AD
   • Delete the corresponding registry keys for the agent. 

Step 3: Reinstall the Agent

1. Download the latest version of the agent from the migration/management tool portal.
2. Reinstall the agent on the device.

Now Check if the Device Re appears under Ready device section.
