Replaced a domain controller that was also the primary DNS server.

Now when I NSlookup from a workstation OR from the DC itself, nslookup resolves the FQDN exactly 50% of the time (every other query)

To wit...:

C:\>nslookup
Default Server:  ourdomain.k12.oh.us
Address:  10.5.41.11

> exit

C:\>nslookup
Default Server:  crldc02.ourdomain.k12.oh.us
Address:  10.5.41.11

> exit

C:\>nslookup
Default Server:  ourdomain.k12.oh.us
Address:  10.5.41.11

> exit

C:\>nslookup
Default Server:  crldc02.ourdomain.k12.oh.us
Address:  10.5.41.11

> exit

C:\>nslookup
Default Server:  ourdomain.k12.oh.us
Address:  10.5.41.11

> exit

C:\>nslookup
Default Server:  crldc02.ourdomain.k12.oh.us
Address:  10.5.41.11

> exit

C:\>nslookup
Default Server:  ourdomain.k12.oh.us
Address:  10.5.41.11

> exit

C:\>nslookup
Default Server:  crldc02.ourdomain.k12.oh.us
Address:  10.5.41.11

It is ALWAYS finding the address, but it is not resolving to the server but 50% of the time.

When I set the secondary DNS server as primary on the workstation, it gets it 100% of the time...

This does not seem to be a workstation configuration issue, since the same behavior exhibits itself on the Domain Controller as well....

I have cleared DNS cache on workstation and server.

Thanks for your insight, experts!
