Need three things:
1) verify client version ("cat /proc/fs/cifs/DebugData")
2) describe server version (if you don't know it, the NOS and OS
version reported
by the server should also be visible if you "cat /proc/fs/cifs/DebugData")
3) confirm whether or not the mount option (perhaps misspelled), which
is presumably not recognized, is logged in dmesg (you can type "dmesg"
in a bash shell to display the error log).
