[Samba] Ubuntu upgrade, now unable to access shares or join domain

[Robert Steinmetz]

I just did a do-release-upgrade on my Samba DC from 18.04 to 20.04 the 
upgrade went well however now I cannot access my domain from my windows 
machines.
smbd and nmbd are running on the DC. smbd version 4.11.6-Ubuntu

Initially I was getting an error that my Domain was not available. I 
can't access any of the shares.

I removed one computer from the Domain to try to rejoin it. I was able 
to remove it but when I try to rejoin from Windows I get an error "The 
request is not supported."

I can apparently log in to the domain users on other machines, but not 
access the shares.
