Windows XP explorer crash

[Rodrigo Schramm]

Hello,

The windows explorer crash when I do a right-click or CTR+C (copy).
This happens after I put the client machine (Windows XP Professional) in Domain (with Samba) and access with normal user privileges.
If I do loggin with Administrator privileges, this error does not happen.
I think that is a permission problem. But I don't know how to fix this problem.

Can anybody help me?
