directories creation troubles

Well....seeing that no one has answered my question, I'm posting it 
again (maybe the message just passed unnoticed   ;-)   ).




I've just finished setting up a samba 2.2.6pre2 installation on a SGI
running IRIX 6.5.16.
I've discovered that logging on a win2000 client, if I create a new file
on a test share everything works but when I try to create a new
directory I get the following error on win:

Impossible to create the folder "New Folder"
Impossible to find the specified file.

Increasing the log level and doing the same operation I get the
following error

[2002/10/08 14:40:18, 5] smbd/filename.c:(119)

Any ideas ?

P.S.
I've installed 2.2.6pre2 because I thought it would have solved the
problem which appeared already in the 2.2.5 version I had previously
installed.
