AD integrated DNS means DNS is part of .dit database and it gets replicated to every other AD integrated DNS servers via AD replication.<br />All domain controllers are authoritative for their DNs name space, and DNS is part of again the .dit database, it makes sense to point the DC/DNS serer itself as Primary DNS since DC/DNS server has the full DNS zone data within the database, choosing closest neighbor as alternative DNS is also very good practice.<br />I manage medium and large networks and all configured this was, and working flawless (-: so far over years<br /><br />There are many articles will tell you do it the same way <br />Check out the George website he has great links to most good KB’s<br />http://blogs.dirteam.com/blogs/jorge/archive/2006/06/16/How-to-use-and-configure-DNS-in-an-AD-environment_3F00_.aspx<br /><br />Thanks for reading my blog <br />best<br />ozOz Casey, Dedealhttps://www.blogger.com/profile/12226180672457689907noreply@blogger.comtag:blogger.com,1999:blog-3179219424167705024.post-85389254287694023552009-05-08T11:48:00.000-07:002009-05-08T11:48:00.000-07:00I should probably clarify.

I read a few places say that only the "primary" DNS server should point to itself (and have no alternate DNS), while all the rest point to the primary DNS first, then to each other for the alternate.Bert Millsnoreply@blogger.comtag:blogger.com,1999:blog-3179219424167705024.post-36571061919207677092009-05-08T11:40:00.000-07:002009-05-08T11:40:00.000-07:00Thanks for the info.
