Hi Bjoern,
in general there is no problem with suse samba etc
ich have very large samba domains up and running, but dont forget
samba 3 is acting like win nt 4 server ( pdc )
its not an active dir controller as win 2003 server
if you need acitve dir for i.e exchange version higher than 5.5
you have to wait until samba 4 gets released, so think about that before
your migration.

at a look at your logs this seems a network problem
have you any firewalls enabled on the suse or/and on the win client?
-Transport endpoint is not connected
for testing do not use this parameters

use sendfile =
large readwrite =
max xmit =
hosts allow =

your conf does not look very logical to me
why dont try edit the suse default conf

create mask = 0777
directory mask = 0777
dont do this in global

perhaps you should study more in the smb faqs which are online in german
too, ther are easy examples in it for testing
and migration examples.
dont mess around with groups etc at starting with samba

Best Regards
