Here it comes,

VPN is a tunnel you set up between the client that wants to access your network and a RRAS (Remote Access Server). The traffic in this tunnel is encrypted. So you can let any protocol through this tunnel, even RPC or SMTP and so on.

Extranet is a website that you publish to your users and customers. You can let people only make a connection to your webserver at ports 80 (HTTP) or 443 (HTTPS).

If you want users to simply connect to your network, without extra configuration, use Extranet, buet be aware that the only thing you can use is a webserver. If you would like your users to have a secure access to your network and don't have a problem with configuring those pc's, use VPN.

Hope this helps...

Both definitions above are correct, however I think it's worth clarifying some points...

A VPN is a tunnel over the Internet (or any network for that matter) through which you can pass data. This data is transparently encrypted at one end and decrypted at the other. A VPN can link an individual PC to a corporate network or link two networks together. Microsoft have implemented VPN technologies into their most recent operating systems but most companies prefer to use VPN hardware (often combined with routers or firewalls) to link networks.

An Extranet is basically part of your network, typically a Website, than can be accessed by authenticated users from outside your network (beyond the firewall). Your users would need to provide a valid username or password. Extranet data transmitted over the Internet can also be encrypted using other technologies such as SSL.

Hope that helps.

Extranets and VPNs both involve securely extending access to network resources out via the Internet.  The term "VPN" refers both to some technologies for doing this, and to the common case where the remote accessors are part of the same enterprise as the secured resources -- branch offices, travelling/remote employees, etc.

What distinguishes an extranet is that the remote accessors are not part of the hosting enterprise; usually, they're suppliers, customers, or some other form of business partner.  Instead of simply extending the enterprise's security perimeter, you've created a zone of shared responsibility where several independent perimeters overlap.
