Samba works with one exception: W7 machine won't reconnect at login

My Samba is working fine. But whenever I reboot my W7 machine, I always have to authenticate to connect to the network drive. "Reconnect at login" is checked. Is there any further configuration that needs to be done on my RHEL6 machine. I am thinking this is nor a W7 but I could be wrong. Please advise. Thanks, Dave
