Hi Ajit Terdalkar!
The device object with the given ID can't be found, causing errors during the registration process. The error code 0x801c03f3 and the HTTP status 400 indicate that the server couldn't process the request due to the missing device object. This could be a configuration issue or the device might not be properly registered in Azure AD. I'd recommend checking the device registration status or re-registering the device.
To fix this device registration issue, start by checking if the device is listed in Azure Active Directory. If it's not there, try re-registering the device. Next, make sure your sync settings are correct, since this is a sync registration. If the device isn't connecting to Azure properly, check the network to ensure it's not blocking access to Azure AD. A reboot of the device might help clear up temporary issues, so give that a try. Also, review any group policies related to device registration to make sure they’re set correctly. If you're using Active Directory, unjoining and then rejoining the domain could fix the problem. Clearing cached credentials might also help, as they can sometimes cause issues. You can also try manually triggering the registration using PowerShell with the command dsregcmd /join. If these steps don't work, check the Event Viewer for more detailed error messages or contact Microsoft support for further assistance.
Regards
