The member server on "real hardware" cannot join, well sort of. When I "join", I get: net ads join -U Administrator Enter Administrator's password: Using short domain name -- DTS***M Joined 'DTMBR01' to dns domain 'dts***m.lan' DNS Update for dtmember01.dts***m.lan failed: ERROR_DNS_UPDATE_FAILED DNS update failed: NT_STATUS_UNSUCCESSFUL And when I "leave", I get: net ads leave -U Administrator Enter Administrator's password: Deleted account for 'DTMBR01' in realm 'DTS***M.LAN' So, I look for what where?
>> Hi Bob, your machine is actually joining the domain, it is the dns adding bit that is failing, try joining again and see if you can connect from another client, if it doesn't, run 'samba-tool dns add --help' and from this work out how to add the computers dns records.

OK, test your member server DNS record in AD:

Run this on the server:

samba-tool dns query <DC FQDN> <DNS Domain> <Member Server FQDN> A

Where:

<DC FQDN> is the fully qualified domain name of the DC i.e. DC.example.com
<DNS Domain> is the domain name you are using i.e. example.com
<Member Server FQDN> is the fully qualified domain name of the Member 
Server i.e. memberserver.example.com

If it isn't there, then add it:

samba-tool dns add <DC FQDN> <DNS Domain> <Member Server FQDN> A 
<IPaddress>

<IPaddress>  is the member server ipaddress i.e. 192.168.0.247
