wins.dat is perfectly filled up with all services from all pc's. This
really works great.....

Here starts trouble..... browse.dat only contains the local
master-browsers of the workgroups and all clients in the server's
workgroup. Now the point is: I can't put all machines in the same
workgroup as everyone sets his workgroup like he wants..... (of course,
I could change some DHCP entries, but I have no knowledge of any
parameter setting windows-workgroup)
But as described, EVERY workgroup is browsed really LAME on Windows,
including servers workgroup. I don't see why, because Samba server is
really BORED (about 0.5% cpu) and shouldn't have any trouble providing
the necessary information.
Second point is that viewing the workgroup list (so directly unter
"Microsoft Windows Networking") is also very slow, although browse.dat
contains all the information needed and it is definitely SENT to
Windows. (according to log.nmbd - i'm already reading at level 3)
Windows should not be the problem as it is using only TCP/IP (so no
clash with NetBeui/NetBios). DNS can't resolve Windows-PC-names (I'm
actually working on DDNS synchronisation with DHCP) but correctly
respondes with "host not found" within msec's. (so should be quite fast)

BTW: It's a standard SuSE installation with official RPM for Samba
2.2.7, without any complicated password configuration. (one public
share (ro, only guest), should just be WINS)
