I looked all over the archives to find an answer to this issue with Samba not loading on my RH7.0 machine.
It turns out that I had deleted the server's name from my /etc/hosts file. I discovered that by tail -f /var/log/samba/log.smb when I saw the "unknown host xxxxxxx", I checked /etc/hosts and volia! It wasn't there. I added the name back in, and restarted Samba. -- To unsubscribe from this list go to the following URL and read the instructions: http://lists.samba.org/mailman/listinfo/samba
