Have a wierd DNS behavoiur and wanted to check my understanding of the flow of DNS in MS DNS servers

  1. A User types in address
  2. If the sites Server 2008 R2 server is the authoritative server it responds with the details
  3. If the sites Server isnt authoritative, it asks via the default gateway, the DNS server of the ISP
  4. If that isnt returned in time, it then queries the root hint server for that domain prefix alphanumeric

In short it does check the root hints last
