I'm not entirely sure how updated Samba is for those devices, but a major problem I've usually always had with a Linux box connecting to a Windows share when the Windows machine had Windows Live Sign-In Assistant installed. Supposedly it's been fixed in the newer releases of Samba. But I'm pretty sure the Boxee Box has it's own rolling releases or something similar, and just might have not released a Samba update in a while.
A quick fix is just to uninstall the Sign-In Assistant, I think it gets installed through Windows Update automatically at some point. So if you don't remember installing it, it doesn't mean it's not there.
