No solution, but to be clear: The nmblookup userland utility can access the remote shares, but the kernel cifs filesystem can't. So something's wrong in the mount system. Are there any messages in /var/log/messages when you mount/umount that mount point? Or in any other log file? When I'm not sure where a subsystem logs, I use "ls -lt /var/log | head" to sort by date right after I stimulate the error, and the relevant files should be near the top of the list.
