Hello!
We’re updating an 2008r2 DC environment (2 DCs) to 2016 but after installing the new 2016 server and promoted it to Domain Controller we get this error when we run
Nltest /dsregdns:
Flags: 0
Connection Status = 1311 0x51f ERROR_NO_LOGON_SERVERS
The command completed successfully
We have transferred the fsmo roles to the 2016 server and demoted and shutdown the old 2008r2 server, installed another 2016 server and promoted it to Doman controller. But when running the Nltest /dsregdns: we get the error on the second DC, if we transfer the PDC to the second DC the Nltest /dsregdns command is Ok on the second (logic), but if we run it on the first DC it will fail again.
We do not see any other errors in the EventViewer.
We have checked the DNS but can’t see anything wrong, we have tried deletes and let it recreate the DC’s entry’s but it seems not to help, and we can see that the DNS works fine.
No SPN doublets or mismatches.
Sites and services look fine.
I got the same problem in my lab VM environment (separated) when I tried to go from 2012r2 to 2016 and the only related thig I can think of is that the two environment is isolated and not connected to internet and Windows is not registered, but we register it in the real environment but it did not help.
Any help is appreciated, I think we have read most of the articles about it but nothing seems to apply.
Thanks, Peter
