• If this is only DC+DNS server
  • Set client DNS setting to local (private) IP address
  • Not 127.0.0.1
• If there is another DC+DNS server
  • Set the primary client DNS setting to the private IP address of the other DC+DNS server
  • Set the secondary client DNS setting to the private IP address of this DC+DNS server

• Set workstation/member server primary to closest/local DNS server
• Set workstation/member server secondary to remote/alternate DNS server
• Do not use public DNS servers
