Configuring DNS servers on NIC card of Active Directory system

If your office is using a Windows Server system as your primary AD/DHCP/DNS box then you need to be a bit careful about how you configure that computers network interface card. Here are a few tips to keep in mind:

  • If you have multiple NICs on the machine, don’t try bonding them together – Microsoft doesn’t recommend it and, as tempting as it may be, it won’t result in any performance improvement so don’t add the unnecessary complication.
  • Don’t rely on a DHCP-based IP reservation for your AD machine – simply hard-code the IP address.
  • Be sure to specify the loopback IP address ( as one of the system’s DNS servers, though NOT as the primary one. See here for details on this one.
