Mouting to samba-share from fstab not working after latest update

[pacmyc1]

Hi.
Im running several PC's with Lubuntu 64-bit.
Until some time ago they were all mounting fine to my samba share (a NAS drive), but after
kernel updates (I've been running apt-get upgrade and apt-get dist-upgrade) the share is no more
beeing mounted on startup.

If I run sudo mount -a from terminal I get

mount: //192.168.0.10/internal: can't read superblock

I can still connect from the PCManFM filemanager by entering smb://192.168.0.10/internal
but then I have to enter the login credentials after each reboot (One more issue here, the credentials are never saved nevertheless that I check
the checkbox that I want to save them)

My fstab entry looks like this:

//192.168.0.10/internal /mnt/NAS cifs uid=****,rw,user=****,password=****,netbiosname=MyPC,port=139 0 0
