If you don't have nounix in there, you may find your NAS/server and your computer try to do magical things with permissions, which can only end in pain.
By putting file_mode and dir_mode you're setting your own mount permissions, just try nounix to prevent the system from over-riding it.
hey mike d,
suggest you add 'nounix' into the mix, i.e :
//10.0. 1.1/Time\ 040Capsule /mnt/mmslab cifs nounix, noserverino, file_mode= 0777,dir_ mode=0777, username= myuserID, password= mypassword 0 0
