The error messages were caused by the fact that the domain name given is a
fully qualified internet domain name, not the workgroup (NT4 domain) name.
NT4 domain names are max 15 characters long. The windows clients are assuming
that because the domain name is a DNS name, that the Samba server should be
an ADS DC. That is why it is making the DNS lookups for the _ldap... etc. DNS
The correct advice to anyone who uses such workgroup names is: Read the
documentation please - use only short (1-15 character) domain/workgroup
The book "Samba-3 by Example" demonstrates how to deploy comprehensive
Samba-based networks". This is what is known as the Samba-Guide on the Samba
The book "The Official Samba-3 HOWTO and Reference Guide" is the mechanic's
repair guide, and provides detailed information regarding the inner workings
of Samba. Chapter 9 "Network Browsing" provides background info that should
help clarify the problem that was reported.
