EDIT
I figured out the problem. Turns out that tab does not show up if you're not logged in as Administrator. Thanks for the help regardless.
I just installed Windows Server 2003 R2 Standard x64 Edition Service Pack 2 on a virtual host. I'm trying to enable RDP, but in the System Properties window there is no tab for Remote like there is with our other servers with the same OS. Does anyone know why and how to fix it?
