Hmph. "taskel install samba-server" apparently installed nothing new on my home ubuntu server, and my Win 7 still can't see it (Mrs.D's still can).
So the problem may be baked in to Win 7 64-bit SP1 (pretty sure Mrs.D's is 32, dunno if she has SP1), or more accurately a patch therein (KB2536276), according to this:

Uninstalling this patch (assuming I even have it) *might* fix it.
