I've done this previously on an old redhat box, but the commands I used then are not entirely applicable for this new centos install
I used something like:
mount -t smbfs -o username=gd,password=psw,uid=gd,gid=gd //nas/bcmv$ /mnt/bcmv
how will this be different on centos? and what additional packages will need to be installed for this to work?
