Hi there, we were migrating an old SBS 2003 box over to a 2012 Standard server. The day after the data transferred the old one burnt out so we were un able to do a proper DCPROMO to remove the old server. I have gone through the whole DNS and removed all records of the old server but it still wont work as the DNS server. No errors etc. except the active directory looking to update. NSLOOKUP says unknown. What have I missed?
