Multiple DNS Errors when running dcdiag /test:dns
Just added a new DNS server. However, I used the old DNS server FQDN and IP address from the server that was removed two weeks ago. Don't know if that's an issue. I was told it shouldn't be.
There are any network problems with the servers or workstations that I'm aware of. The reason I ran the test was that in a previous post of mine I was trying to find a rogue DNS server which the Experts did solve. However during solving that problem other DNS problems surfaced.
When I run ipconfig /all from a workstation all DNS/DHCP servers are correct.
See the attached error. ignore the spcala02.laspca.corp unavailable. That is fixed
If I run NSlookup I get "default server unknown Address 172.17.1.30. Which is the DNS server that was removed two weeks ago and then added back in today.
Hope this make sense

sorry. Attached is the report from the DNS server "dnsfail2" and the new dns server dnsfail3.

Suggestion. What if I remove the DNS role for the new (rebuilt) server, remove it from DHCP, and do a DNSflush. Then change the server IP to a new one. Then run the test on the remaining server?

ok the results are better, but much larger. How do I send the file in one piece?
ASKER
the dnstest is from the new server. dnsfileserver is the old server. I believe they are different? shouldn't they be the same?

So if I'm understanding correctly, we don't have a problem, correct?
See attachment. Do you recommend I select "only the following" and then only choose "172.17.1.33" I have no idea what the other IP is?

I've never seen EE do this before. I accepted the appropriate answers. Why are they asking if there are any objections?
Honestly I don't have a clear picture of when a question will close immediately and when it will go to pending asking for any objections.
ASKER
this is a first for me.

Sorry I didn't make it in to provide assistance on this, but I think a question goes to a "pending" state if you accept one of your own comments, even if you accept it for zero points.
ASKER
Ah, must have done that by mistake. Thanks for clarifying
ASKER
thanks for all the help and patience.
The result you see when you run nslookup is because you don't have a Reverse Lookup Zone with a PTR record which points to the DNS server.
