The Samba logs show absolutely nothing happening which suggests that 
Windows is accurate when it says it can't find or connect to a login 
server / domain controller.

I've been through all the Google searches I can think of and haven't 
found much beyond the local security policy and local registry changes.

I can connect to shares on the computer only when I use a local account.
