We recently upgraded to a new primary domain controller and demoted the old primary to secondary. Since this, all of our virtual machines give an error that a duplicate name exists on the network. I have tried running NewSID on them and changing the name, but the error still occurs. Once it gets stuck as one name, you cannot chnae the name to something else, as it gives and error that I am not connected to the domain because of a duplicate name and tells me to change the name of the machine... which is what I'm trying to do. I can get the name changed if I move the machine off the domain, disable the network card, then rename the machine and rejoin it to the domain after reeenabling the NIC. Once it's back on with the new name, it STILL says there is a duplicate. I have deleted all DNS records and computer accounts for the machine in AD. Anyone have any ideas?
