This machine does not qualify for rejoining ... it has been tampered

Dear Sirs,

I need to get the original machine back into AD. When I try to Join the machine in domain, I received the "This machine does not qualify for rejoining ... it has been tampered" error message.

Removed all computer entries from SCCM. In case the error message is related to something else, please advise how to proceed.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

How are you trying to join it into AD? Did you try to remove it from the domain, then delete the computer account is ADUC and after that rejoin the machine into the domain??

Deleted the AD object and tried to join to domain. Still the same error. Machine Tampered.

Any more ideas. Please suggest
So the machine is in a workgroup now?? If not, make it a member of the workgroup first, then add it to the domain again.
And this is a workstation, right?
