Intergrated active directory DNS windows 2003

paul.haviland.ctr
When you have DNS integrated with active directory you can have more than 1 primary DNS, you don't have a secondary DNS unless you have non-domain computers in your environment. When you set up TCPIP on the workstations how do you get fault tolerance in the DNS settings? You put a primary DNS server xxx.xxx.xxx.xxx, if you put in a secondary xxx.xxx.yyy.yyy you really don't have a secondary DNS server. If you just put in the primary and the primary server crashes how do you take advantage of the other domain controlers that are running DNS

Fault tolerance for DNS? or fault tolerance for Active Directory [which requires DNS to function]?

Fault Tolerance for domain controllers so that if one DC fails, there is another DC which will allow users to log on and obtain access to domain resources requires at a minimum, the Global Catalog role and that the sysvol and netlogon shares are accessible on the network as well as a DNS server to answer queries by clients for resources such as DCs and Global Catalog servers, DHCP server, File Servers blah blah.

For DNS you simply need a DNS server that has an authoritative zone for the domain so that queries for resources can be resolved. DNS servers do not have to be domain controllers, and vice versa but you need both for Active Directory to work.

For more information, visit Microsoft Technet and use the search keywords, DNS zone transfers and Global Catalog Role.
