Firstly, I have no clue about Linux whatsoever, I'm the Windows Domain Administrator here.
The R&D department have a Linux server with some Samba shares set up. I can access these shares fine by supplying a username/password (that the linux bod set up). This works fine, unless the Windows PC is logged in as the domain administrator.
This means that the backup server (logs in as domain admin) cannot access the samba shares.
Don't ask me to post my smb.conf or anything - jsut wondering whether anyone has come accross this before?
