Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

Same mount, no problem in kernel-PAE-3.7.9-205.fc18.i686

Try adding "sec=ntlm" to the mount options.

The error seen with recent kernels is usually "mount error(22): Invalid argument" and adding the sec option fixes it....so this may not be related.

Yeah!  This works:

# mount.cifs //raptor/unix/FEDORA /raptor -o sec=ntlm

Should have mentioned in my first post: the server is a NetGear ReadyNAS (linux-based) storage appliance, not a PC. There is, however, no command-line access to the server's OS; just a web browser interface, with almost no authentication options.

Not to take this too OT, but I've used cifs mounts here because NFS performance sucks with the same NAS--about 300k/second on backups using dump.
