related to thread How to edit /etc/fstab properly for network drive?
i have added the following line to /etc/fstab
//192.168.0.52/public /mnt/PC52/public cifs username=guest,password="" 0 0
if i call sudo mount -a the directory mounts and all works fine, but if i reboot the computer it fails to add at boot, i feel like its something to do with the blank password that i have passed, if i omit the password field completely it prompts for a password during boot and if i just press enter it boots and works
