I have an ESX 4.1 host that crashed. I pulled out the server and replaced it with an identical make/model. I swapped the local drives as well so ESX booted up as if there was never any issue. I removed the host from vSphere before swapping the host. Now when I try to re-add the host to vSphere, it warns me that the host is already managed by another vSphere server.... which is the same one I am trying to add it back to! I say Continue, but I am out of licenses and cannot add it back.
How can I get this machine back into vSphere?
