demoted DC with DNS server role removed still shows up as DNS for DHCP workstations
Several days ago I demoted one of our 4 domain controllers and removed the DNS Server role. Workstations using DHCP list the old DNS server when using ipconfig /all. The DHCP server does not point to the the old server for DNS (that was my first thought). I removed the old DNS server from the "named servers" list on the other DNS servers. However, the old server still shows up as a DNS server for computers using DHCP. Any ideas why the workstations are grabbing the old DNS server as one of its DNS references? All of our DCs are Windows Server 2003.
