Help with auto-mount with samba.

[x0acake]

Hello everyone.

I have edited my /etc/fstab file in order to have it automatically mount a windows network share at startup.

The problem is, that it isn't really working during startup. After I log in, in order to make it mount I have to open the terminal and enter "mount -a".

The following is my fstab file:

#
# /etc/fstab
# Created by anaconda on Tue Jul 19 10:38:18 2011
#
# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info

/dev/mapper/vg_x_user-lv_root /                       ext4    defaults        1 1
UUID=aef76330-25e7-4b5a-b2bc-6f76dd890c0a /boot                   ext4    defaults        1 2
/dev/mapper/vg_x_user-lv_home /home                   ext4    defaults        1 2
/dev/mapper/vg_x_user-lv_swap swap                    swap    defaults        0 0
tmpfs                   /dev/shm                tmpfs   defaults        0 0
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                   /sys                    sysfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
//10.0.0.2/G_DRIVE   /media/GDRIVE   cifs   guest,_netdev,gid=500,uid=500   0 0

I suspect this has something to do with my laptop not having made a network connection when the entries are mounted, but I'm not sure. How would I go about finding out about any errors that this might have happened or how would I go about fixing this?

Thank you.
