If you were getting permission denied while mounting a w2k3 share onto a linux box then here is a suggestion to get around that
• On the Win2K3 server select Domain Controller Security Policy from the Administrative Tools menu/x-tad-smaller>/color>
/x-tad-smaller>• Navigate to Local Policies|Security Options/x-tad-smaller>/color>
/x-tad-smaller>• Disable “Microsoft network server: Digitally sign communications (always)”/x-tad-smaller>/color>
/x-tad-smaller>• Since FC2 you will also need to disable “Microsoft network server: Digitally sign communications (if client agrees)”/x-tad-smaller>/color>
/x-tad-smaller>• You can wait for the policy to propagate or run gpupdate from a command line
