If not, would that solve the original problem? Thanks Alex -- This message is intended only for the addressee and may contain confidential information.

However I still have huge CPU utilisation from winbindd and smbd just fromtrying to long in a single test XP machine. I have the MooseFS guys on the case as well. Should I put them in touch with you or vice/versa? Many thanks for your gracious assistance, Alex -- This message is intended only for the addressee and may contain confidential information.
