Hello all,
To Start off, I have 3 AD controllers. All three were Windows Server 2008 32-bit Standard. I recently completely replaced ( but changed the name and IP back to what it was) our DC2. I used the Netdom method for doing so without issue.
The new DC2 is now using Windows Server 2008 R2 -64bit Standard. Ever since then when I go to test DNS resolution, the Recursive lookup fails. Now, trying to look up external web sites is starting to fail. If I set my dns server in NSlookup
to google a or b, it works fine. Where is the first place to start in tracking down DNS lookup and recursion issues. While I've worked with DNS in the past, I haven't had many issues.
Thanks in advanced.
