I'm in the process of tidying up after a migration, I ran BPA on the only DC and received the above error.
DNS is on the adapter has only a primary entry of 127.0.0.1 and no secondary. Forwarders are set to 8.8.8.8 and 8.8.4.4.
The other servers (Exchange and RDS) point to the DC and have no secondaries.
I'm wondering if this setup is okay?
Richard, that BPA assumes you have two Domain Controllers but in the SMB space we most of the time have only one. You can ignore that 'error'.
