Symptom

When you deploy Windows on a device, these events are logged:

Log Name: Microsoft-Windows-User Device Registration/Admin  
Source: User Device Registration  
Event ID: 307  
Level: Error  
Description:  
Automatic registration failed. Failed to lookup the registration service information from Active Directory. Exit code: Unknown HResult Error code: 0x801c001d. See https://go.microsoft.com/fwlink/?LinkId=623042

Log Name: Microsoft-Windows-User Device Registration/Admin  
Source: Microsoft-Windows-User Device Registration  
Event ID: 304  
Level: Error  
Description:  
Automatic registration failed at join phase.  Exit code: Unknown HResult Error code: 0x801c001d. Server error:. Debug Output:\r\n undefined.

Here is an example of the event IDs:

Cause

These event IDs occur when the infrastructure isn't prepared for Hybrid join. When the device tries to do Hybrid join, the registration fails, and the events are logged.

Resolution

If the infrastructure is in a non-Hybrid join environment, these event IDs are expected during Windows 10 deployment. They can be ignored.

If you have a Hybrid scenario, see Troubleshooting Microsoft Entra hybrid joined Windows 10 and Windows Server 2016 devices for troubleshooting steps.
