What are you connecting to ? 
A Samba AD DC or a Windows DC ?

What dns domain is the DC in ?
is it 'mydomain.myorg.com' or 'myorg.com' ?
Your Unix domain member must be in the same dns domain, you should not
need to add anything to /etc/hosts, it should use dns to find
'myserver'.

This is what I get:

pi at rpidc1:~ $ time smbclient -d 2 -U SAMDOM\\rowland -L

We will cross that bridge when we come to it and if required, it will
probably need to be posted somewhere, this list strips attachments.
