I think you can add something like the following to your fstab (back it up first) and go from there. I was having some similar issues a while ago and I think it's something to do with permissions issues between linux and ntfs drives.
//192.168.1.103/bigmamaBU /mnt/bigmamaBU cifs iocharset=utf8,dir_mode=0775,gid=1234 0 0
Here's my entry from fstab, just note I'm using the drives serial instead of network path (in your case)
UUID=DC145AE1145ABE68 /media/500GB ntfs-3g uid=500,gid=500,100,umask=000 0 0
