Suppose I have a domain called XXXX.com
This domain has many things running on it such as:
- Domain controller (we'll call the server "Domain")
- Microsoft Exchange Server (we'll call the server "Exchange")
- Intranet Application (we'll call the server "Intranet")
Obviously, the Intranet application has to be accessible to the outside net. Though, I need to secure the Domain and Exchange servers from outside access. That is, I would like to be able to remote desktop into these servers from anywhere but without someone outside of my organization to remote into it. I don't even want outsiders to have the possibility to get to the log in screen.
Note that all these servers are behind a firewall.
Can someone please give me a robust solution for this problem?
