Device still has Jamf, but lost the record on the IT side

[dosel99]

Hello all,

3 of our devices were supervised and managed, but the Jamf records on our end were deleted while the devices were still active. So the devices still have Jamf on the system, but now phoning home is pretty weird. We were able to restore one of the records, but it appears to be only managed now. On this restored record, we are unable to push any commands or policies to the device that are normally available by default (Lock Device, Send Blank Push, etc.).

Is there any way to get these devices reconnected to our system, or should we bag it and just re-issue new devices to these users?

I'll be checking this all day so please feel free to ask any questions about anything I might have left out. Thanks!

It the records were deleted, you will need to re-enroll the computers, there is no other way and the MDM connection is broken. 

You don't necessarily have to wipe the computers to re-enoll. If the computers were enrolled via User Enrollment, delete the existing MDM profile and then re-enroll the computer. 

If they were enrolled via Automated Device Enrollment. Open a terminal and run the command

sudo profiles renew -type=enrollment

A notification will appear prompting to enroll the computer. Click on the notification to start the enrollment again. 

FYI many of your policies will run again, even "Once per Computer" since this is, effectively, a new computer to Jamf. And and Static Groups or Scopes those computers were added to will need to re-added again.
