It depends on what you really need. If you're working local to the server, use the shares instead of the Remote Access web site. (There's a link to the server shares on the desktop of every computer you've installed the Windows Home Server connector on.) If you're talking about remote access, Windows Home Server isn't designed to serve the role that SharePoint does, so there's nothing built in to the product to let you do what you're asking. In the latter case, it's possible (but unsupported and not highly recommended because there are some security considerations) to turn on WebDAV and expose one or more shares directly to remote users who authenticate against the server. For the latter, you'll want an add-in called "Web Folders 4 WHS" which takes care of most of the configuration for you.
Bottom line, though, is that if you want SharePoint, you're better off with SharePoint (and maybe Small Business Server).
I'm not on the WHS team, I just post a lot. :)
