Samba shares are sometimes difficult to work with through the Ubuntu UI. As such you can follow these steps to mount a SAMBA share in Ubuntu:

Install cifs-utils

sudo apt-get install cifs-utils

Create a mount point

sudo mkdir /media/drive

Mount the share

sudo mount -t cifs //192.168.1.151/Share /media/drive -osec=ntlmv2,domain=WORKGROUP,username=YOUR-USERNAME,password=YOUR-PASSWORD
