[Samba] After joining domain, Samba uses the workgroup name, not the FQDN when running the net ads command

192.168.127.129 is the core DNS server. It forwards anything in the
windows subdomain straight to the DCs, so it doesn't matter if this client
is pointed at the DC or the main DNS server. Either way, it still does the
wrong behavior, which is use the short .WINDOWS instead of .
WINDOWS.CORP.XXX.COM
I removed all .tdb files, purged /var/cache/samba, removed /etc/krb5.tdb,
and deleted the computer account out of AD.
I have a feeling this line is significant, but I'm not sure what it means:
