I want to set up my server so that I can use RDS for up to 20 users. I’m currently running Vista and I’m somewhat of a novice when it comes to this but I’d like to get clarity on what exactly I need to accomplish this. Can I just get Terminal Services and add it to my existing server? Do I need to trash Vista and install WS 2008? I have a third party email server I’m running so I can I still use that if I install WS 2008?
