Thanks, Bigpaws. I followed the procedure you outlined but I still couldn't get access. I think I'm not ready for the Vector prime-time, since I get access with any other Linux system. Too bad.
I've found in several instances that, unless you have either a correct /etc/hosts file or a local DNS server, the mount command needs IP addresses instead of machine names. I've also found (no idea why) that combining username/password works better than specifying both separately.
mount -t cifs -o user=admin%xxxxxxr //10.1.0.10/backup /mnt/smb
The above only works if the 'backup' directory is already set up as a share.
I have no idea why, but I found the user=<name>%<password> works more reliably than specifying user= and password=
