Microsoft security administrators have always been a bit wary of publishing Terminal Servers to the Internet. And for good reason - there was no ability to pre-authenticate connections or use policy to determine which users could access which Terminal Servers. The lack of pre-authentication was an especially difficult problem. Without pre-authentication, anonymous users could leverage their anonymous connections to compromise the published Terminal Server. A compromised Terminal Server is perhaps the most dangerous exploit possible against your network, as the attacker has access to a full operating system to launch his attacks. Windows Server 2008 provides a solution to this security problem: Terminal Services Gateway. Using a Terminal Services Gateway, you can pre-authenticate users and control what Terminal Servers users can access based on credentials and policy.
