Remote access to one folder?

I have a server with windows 2003 server on it.
I have remote access set up for the exchange mail and remote desktop;
They are accessed by http://serverIP/remote and http://serverIP/exchange

I want to just share one folder to someone remotely, without them logging in to a remote desktop.

Not sure how I should do this? Can they somehow map it as a network drive over the internet?

Like map \\IpAddress\folderName kind of thing?

Blah, I guess this sounds kind of stupid. I've just never had to do it before really.

But anyway... The easiest way to do it would probably be to create a web site in IIS and configure the site to redirect to a Virtual Directory: the location of the share you want to make available. Then whenever someone visits the web site, they'll get redirected to your shared folder.

I'd STRONGLY recommend you configure this IIS site to require SSL encryption (https://), and the same goes for the sites you're already publishing.
