[Samba] Delete directory on mounted system

[CONTACT]

Hello, I'm french so sorry for my mistakes.

I have samba server 2.2.8 on mdk and one PC on Fedora Core II in local
network.
I have mounted some smb directory on my FC2 .
All work fine but just i can't delete any directory on my FC2 however i
have all the rights.
That made 4 days that I seek but I found anything.

Thank for your help.
