Dwain Pipe Posted June 29, 2019 Share Posted June 29, 2019 I'm running Win 2016 Essential on a HP Gen 8 Microsoft. I've recently expanded my LAN and can now run 3 cables to my server, so I've cabled the iLO, and both LAN NICs. I've then created a NIC team using the default configuration. The NIC team has got green ticks on all the settings, and the server seems happy :-) Then the Best Practice Analyzer runs and gives me an error... "The network adapter <my NIC Team Name> does not list the local server as a DNS server; or it is configured as the first DNS server on this adapter." With the really helpful advice to: Resolution: Configure adapter settings to add the loopback IP address to the list of DNS servers on all active interfaces, but not as the first server in the list. So I've done as asked... 192.168.1.1 is my router that is configured with both my ISP and Google DNS services. But, you've guessed it... the Best Practice error remains. The server still seems happy, I'm getting no obvious network errors, although some of my client PC occasionally get a DNS probe error, but I reload the webpage and it works. Any other ideas please?

nrf Posted June 29, 2019 Share Posted June 29, 2019 (edited) so just reverse them and you will be cool. I think there is a 'not' missing from the error message. after all these versions of essentials you would think they would spot that.

Dwain Pipe Posted June 29, 2019 Author Share Posted June 29, 2019 I get more error from the BPA if I reverse the settings. I swapped to... All the errors are basically complaining that 192.168.1.1 is not a DNS server (it's a router). Link to comment Share on other sites More sharing options...
nrf Posted June 30, 2019 Share Posted June 30, 2019 (edited) but does your router provide dns service? have you checked its settings? it can be both a router and a dns server. how about showing us the errors? my essentials2016 is clean in the BPA and I have it set up as 127.0.0.1 and 192.168.1.1 where my router does provide dns. at some point you may want to live with some of the bpa stuff if you are sure your setup is ok. on 2012r2 essentials it was always complaining that I didn't have a secondary domain controller, I ignored that.

Dwain Pipe Posted June 30, 2019 Author Share Posted June 30, 2019 My router uses my ISP and Google DNS and provides that service on 192.168.1.1 When I swapped the DNS setting around the BPA gives more errors that 192.168.1.1 must provide: Global Catalog resource records LDAP resource records PDC resource records resolve names in the forest root domain name zone resolve names in the primary DNS domain zone resolve Kerberos resources records for the domain controller Where as when the IPs are the other way around I only get one error, the loopback should be second error.

nrf Posted June 30, 2019 Share Posted June 30, 2019 I see no reason to be concerned about it. are you sure you are up to date? Link to comment Share on other sites More sharing options...
Dwain Pipe Posted June 30, 2019 Author Share Posted June 30, 2019 Yes, fully up to date. I think I'll exclude the BPA error from the health check. Link to comment Share on other sites More sharing options...
schoondoggy Posted June 30, 2019 Share Posted June 30, 2019 This is a bit dated, but worth a look: https://social.technet.microsoft.com/Forums/office/en-US/4420de24-3af3-43dd-8973-addfe989689f/win-2012-dns-server-bpa-error-cant-be-fixed?forum=winserveripamdhcpdns Link to comment Share on other sites More sharing options...
nrf Posted June 30, 2019 Share Posted June 30, 2019 yes I mentioned about a previous version wanting a backup domain controller. that one was server standard + essential experience somehow my essentials 2016 instance has the exact same settings and is not firing that best practices complaint.

Dwain Pipe Posted July 4, 2019 Author Share Posted July 4, 2019 I had the thought about the IPv6 causing the issue when I was troubleshooting the issue in the first place. I disabled IPv6 in the teamed NICs adapter properties, but it made no difference. I could try set the IPv6 DNS with the loop back second and then disable it, as perhaps the BPA is reading the settings regardless. Link to comment Share on other sites More sharing options...
