mount via etc/fstab doesn't work

[nafihsus]

I have following entries in /etc/fstab trying to mount 4 directories of my nas. The first two work fine, the 'pictures' and 'cenk' directories fail.

eldenas:/music /mnt/nas-music nfs
eldenas:/video /mnt/nas-video nfs
eldenas:/pictures /mnt/nas-pictures nfs
eldenas:/cenk /mnt/nas-cenk cifs user,uid=1000,rw,suid,credentials=/etc/credentials 0 0

I use Ubuntu 9.1.
Any help is highly appreciated.

Knowing that this might be the wrong forum to ask a related question:
I do get access from my win7/winxp clients to the directories under 'music' but I can't see any music files. No issue from ubuntu clients.

dont get headache with fstab, install and use mountmanager to deal with partitions and devices rights ( system admin mountmanager)
