Setting Network Profile from Public to Domain on Core

Get Network interfaces profile

Get-NetConnectionProfile

sometimes when you recover a VM from backup it likes to change to Public even though all the other network settings were recovered successfully.

NLA Reset via Disable/Enable NIC

first thing to try is simply disable and re-enable the NIC once connection to a DC is verified.

Get-NetAdapter | Disable-NetAdapter
Get-NetAdapter | Enable-NetAdapter

All else fails, Set the DNS Suffix

If the NLA still refuses to show Domain status, try setting the DNS suffix…

Get-NetAdapter Ethernet | Set-DNSClient -ConnectionSpecificSuffix "Zewwy.ca" -UseSuffixWhenRegistering $true

Then, again disable, enable the interface.

It should go back to DomainAuthenticated. If not verify the computer is still actually authenticated with a DC with nltest.

Hope this helps someone.
