Funny Problems with woody/samba 2.2.3a-12.3/Windows-Network

[Kim Armann <kim@aw-consultancy.de>]

Hi there,

I have a strange Problem:
If I copy a file wit a long filenemae, e.g. index_innen_ie.php to a share 
on the samba-server I get 2 (two) files on the server. The first is 
index_innen_ie.php the second something like INDEX~7$.PHP

Any Ideas ????
