Just going through the advised BPA scan on 2012 Essentials server and received a couple of errors.
Are these cause for concern?
Error 1 - I have added the loopback address but it still gives this error.
Error 2 - Do I need to add credentials to DHCP?
Error 1:
The network adapter Ethernet does not list the local server as a DNS server; or it is configured as the first DNS server on this adapter.
Impact:
If the loopback IP address is the first entry in the list of DNS servers, Active Directory might be unable to find its replication partners.
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.

Error 2:
Secure dynamic Domain Name System (DNS) update is configured, and a domain cotroller is running on the same host as the DHCP server, but credentials for DNS update are not configured.
Impact:
DNS registrations can fail if credentials for DNS update are not configured.
Resolution:
By using the DHCP MMC snap-in, configure credentials for dynamic DNS update.
