Remote access solution

[Orlando J. Cano]

I have recently been assigned to join efforts with our Network group in coming up with 
a secure  remote access solution for our Network. This will involve accessing servers 
in our DMZ. I was wondering if this securityfocus community could elaborate on how 
secure VNC, Freevision or Terminal Services are or better yet recommend another 
solution. 
Any comments would be greatly appreciated.

Thanks
