The domain and workgroup are named differently. But I think I see
what's happening...the domain controller isn't the clients primary DNS
server. Always comes down to DNS...

What I don't get is why DNS would matter when logged into the domain
but not when logged in locally...the computer is a domain member
either way and the IP settings are the same...
