Server 2012 BPA errors - DNS - DHCP - NTP
I see 3 BPA errors in Server 2012. This is a small domain with only one server so it's a DC, DNS & DHCP. Are these errors fixable. Should I be concerned on a small domain like this?
Error 2 - Since it's a one server domain I didn't add a 2nd entry for DNS. One article I read advised against adding the loopback address 127.0.0.1 so this is considered unfixable, right? ON the other hand, this article supports using the loopback. Either way the BPA doesn't seem to be satisfied since the loopback was listed as 1st DNS prior to working on these BPA errors.
Error 3 - I added a user in the Administrator's group for DNS update but it didn't seem to make any difference. It already was using a user in the Administrator's group.
Error 1 - I setup NTP servers as per this video. The servers were set to reliable and show up in the query so not sure why that doesn't show on BPA. I also tried the old Microsoft Fix-it.

Error 1 - The PDC emulator master Server-xxx.xxxx.local in this forest should be configured to correctly synchronize time from a valid time source
Error 2 - DNS: DNS servers on NIC1 should include the loopback address, but not as the first entry.
Error 3 - DHCP: Credentials for DNS update should be configured if secure dynamic DNS update is enabled and the domain controller is on the same host as the DHCP server.

Will we are using 8.8.8.8 on the router so I guess that would be a decent DNS forwarder. Should it be added as a conditional forwarder & stored in AD?
I setup a time source as per the Experts video but it didn't seem to matter. They were set as reliable & I can query & see them as shown above.

Thanks Thomas. the Powershell BPA cmdlets didn't run for me and but refreshing a role in the GUI did resolve 2 of my issues. I was trying to refresh from the local server pane and evidently that didn't work even after issues were resolved.
The only issue I see now is #2 & my guess is that it doesn't go away for a single server domain.

I have ipV4 setup correctly. Is it advisable to use a static ip for ipV6 on such a small domain?
I added current ipV6 (it's DHCP), & ipV6 loopback for DNS but it still doesn't' satisfy BPA.
Should I just ignore the error?

The cmdlet you suggested works fine. The one in the BPA article you suggested did not (i.e., I get lots of warnings).
Yes I would like to resolve the DNS error but I don't see a solution with a single server.
Get-BPAModel | Invoke-BPAModel
"WARNING: The EngineReport.xml & Result.xml files were not generated successfully..."

OK that works for me. I excluded it from my results too. If you can't get it to clear with 2 DCs there's no chance I am clearing it with one. Perhaps it works if you have DNS servers that don't reside on DCs.

Thanks for all the help. It's too bad that one warning has to be hidden to make the BPA panel show as all green,
Randy
yes it is
did you have any warnings in the bparesults for DNS?
I found a couple in mine rooting thru them now.

Error 2 is not resolved by adding loopback as secondary DNS.
error 3 Dynamic DNS is enabled in IPv4 DNS properties tab of DHCP
