To mount a Windows Samba drive on Ubuntu for the current user, you need the following steps:
sudo apt-get install cifs-utils
sudo mkdir /mnt/share
sudo mount.cifs //sambahost/sambaDir /mnt/share -o user=xxx,password=xxx
where the sambahost is the samba server ip address or hostname that you should be able to ping it, sambaDir is the samba directory you want to access, user/password is the credentials you use to access the samba server. I found that I don’t need the windows domain name part in the user field.
