[Samba] WIN2k profile problem

[Christian Cernuschi]

I have samba 2.2.3 with several win2k (sp2 srp1) and generally Roaming
profiles works.

Sometime after having logged It says that it's impossible to write to my C:
drive from \\server\\etc etc and then he doesn't load profile correctly.

So i have to log in with Administrator (in the PC and not the Domain) remove
"myname.bak" folder under "Document and settings" and then it starts working
again...

Why? Any suggestion?
Thank you

Christian
