Azure AD Join is failing with CAAA2000C

Trevor Hopkins 0 Reputation points

I have a problem joining my Windows 10 laptop to my AAD domain. AAD Domain join results in an "oops something went wrong - error caaa2000c. AAD audit logs show the device as being successfully registered, immediately followed by successfully unregistered. I am a Global Admin.

The device was originally Hybrid-Joined although AD has now been decommissioned. I have removed the device from both Intune and Azure AD but this has not resolved the problem. The Device was originally registered for AutoPilot but I have also removed this registration to try and resolve this issue. I have also turned off MFA temporarily on my user account as the local device logs indicate a "user interaction required" issue.

Have ran the enrollment troubleshooter tool and this reports everything is in order for a Domain Join to happen. I've also tried dsregcmd /leave force and dsregcmd /join force, which hasn't worked either.

I don;t know what else to do - I have googled the hell of this issue and tried everything I have come across!
