[Samba] Win98 SE - problem with copying to shares

[jkulow at imap.dentalmail.de]

Hi all, 
i have problems when copying to my shares from win98 to samba on redhat 7.3. 
Win starts copying but bracks with error, that the share is no longer 
available or is removed! 
 
does anyone know what that means??? 
 
I can create folders and browse through the shared folder, I also can delete. 
 
Any hints how i will be able to copy to that share? 
 
Thanks, 
 
Jochen
