My company uses a sub domain for a satellite office, all works fine and replication takes places etc etc.
The problem I had was with DNS. I’m based in Contoso.local and I cannot ping any device the sub-domain Sub.contoso.local without fully qualifying the domain.

DNS cannot route the command where as if I type
it works fine.
I’ve checked DNS on Contoso.local and there are conditional forwarders to Sub.contoso.local:
So how can I get around this?? The answer is to add a DNS Suffix locally or to all the domain devices via group policy:
Computer Policy > Policies > Administrative Templates > Network/DNS Client > DNS Suffix Search List.
Then GPUPDATE /force your client and run IPCONFIG /ALL and you should see:
