I have fedora core2 with samba-3.0.7-2.FC2 (and an other server with samba-
3.0.3-5 has the same problem.)
When i connect with my windows xp (sp1) client to the share on the smb server 
and try to order the files and directories by name they dont show up on the 
right order. When i do this with an windows 2000 client. it all works correct. 

My smb.conf is ass following.
