What's the NAS feature that allows Windows to map it as a network drive?

[monkeynetman]

I'm trying to look for a NAS device that can act as mapped network drive for my Windows machine. What is that feature called? I know many of them can do Samba, but I preferably want to be able to map it as a network drive, but I keep forgetting what it's called for that feature.
