Terminal Server: On DMZ or Domain - Pros and Cons


We want to implement Terminal Server in our organization in order to let users access one or two application from outside. Since we are very concerned with security, we would like to have some advice on where to put this server, in the DMZ zone or in the Domain.  Ideally, we would like the user to authenticate via Active Directory and run the application with those credentials. We are talking here of probably 5 users, once in a while, that will need to access the application out of town. How feasable it is to have a user connect to Terminal Server in the DMZ, authenticate thru Active directory and launch an application within the Domain?

Your tags say Server 2003 so I did not originally include any info on 2008 TS.

Well, yes I'm on Server 2003 but according to what I understand, 2008 offfers a much better solution. I  may be interested in upgrading to 2008.

2008 offers better security than 2003 and you can split roles between different servers.
