[Samba] Samba-Cups: all works except browsing when printer is not defined in smb.conf

[Koen Linders]

Cups 1.2.7 
Debian Etch with Samba 3.0.24
Clients: WinXP SP3 (with Firewall completely off for testing)

When I define a printer specifically in smb.conf, they show up as shared
printers in WinXP. But when I follow the normal way (see below) to load all
from cups they don't.

I followed mainly the latest SAMBA-HOWTO (chapter 21-22)

The only error I see in log.smbd when accessing the Printers&Faxes where
they should be, is:
[2009/06/30 11:13:50, 0] smbd/service.c:make_connection(1111)
  mpi025 (192.168.1.106) couldn't find service
::{2227a280-3aea-1069-a2de-08002b30309d}

When I add them by name instead of via browsing all works, but I wish to
understand what goes wrong and where. 
This works: 
runas /netonly /user:root "rundll32 printui.dll,PrintUIEntry /p /t3 /n
"\\newton\2420N-240"
rundll32 printui.dll,PrintUIEntry /in /n "\\newton\2420N-240"

Any suggestions would be very welcome.
