samba - Jun 2003 - testparm is telling me something but i dont know what.

Hi all
I try to get Samba running on the recent Debian stable release.
All upgrades have been done and Samba was included in the OS Installation.
I use the  Samba version 2.2.3a-12.3 for Debian.
smbd and nmbd are starting automaticly when the System is running.
The smb.conf is still the one from the installation, nothing edited yet.
Here are the errormessages that i get if i try testparm and smbstatus.

Please help me to get rid of these messages :-).

THX for help from Ford Prefect
