DNS forwarding and root hints error.

1,160 · September 21, 2017

Hi All.

My data center provider had to physically move their infrastructure from their existing location to their new buildings. Extensive planning was done and I was involved and on paper, everything should have been fine. However, on first start up on the new location, sysprep ran on several of my servers including our DC's. We recovered from backups to the state just before the move but they were in USN rollback so I involved Microsoft and we were able to recover the domains and ensure replication was working.

I have since been tidying up DNS as we had a site that was unable to access outside sites and have managed to clear all the issues apart from this one from DCDiag /test:DNS

I am currently using public DNS for forwarders on this DNS server, this is temporary while we migrate to a new line over the next few weeks.

I have also tested removing the forwarders and running the tests again but I get the same results, strangely though from the server, browsing is now fine and would suggest forwarding is working? Under the forwarding tab, I have updated and can resolve all the servers so I now have the latest IP addresses and the forwarders also resolve and validate.

Although this appears to be working (I also have a clean DNS event log) I am concerned that further down the line I will have issues that could be resolved now.

what in your configuration is making DNS query this?

            DNS server: 202.12.27.33 (m.root-servers.net.)
               1 test failure on this DNS server
               Name resolution is not functional. _ldap._tcp.DOMAIN.local. f

It should not query domain.local externally....this is where your fail is. I don't know your setup fully, so I can only assume that you don't have AD dns setup properly or you have other issues there. External DNS will never resolve internal names.

1,160 · September 21, 2017

I did notice this and cant find any trace of this in DNS or ADSIEdit, can you point me in the right direction where it may be?

11,094 · September 21, 2017

you aren't going to find it in adsiedit or dns....at least what you are looking for. your system is trying to find your local domain on a external dns...

entries are missing on your dns, dns not setup correctly, replication is not happening. You have to look to see if your dns is replicating properly, eventviewer logs will help here.

I'm not seeing any replication issues, ran the following on all DC's and the results are all successful, all had the same results.

repadmin /showreps

Also ran dcdiag /v, no issues her that I can see - Apologies for the lenght).
