Hello jacobstr,
To change the server out of remote desktop administration mode you need to remove it from add/remove programs. You can then readd in TS Administration mode
1. Remove Terminal Server from Add/Remove Programs/Windows Components.
To install Terminal Server on a computer running Windows Server 2003:
1. Click Start, click Control Panel, and then double-click Add or Remove Programs.
2. Click Add/Remove Windows Components.
3. In the dialog box, select Terminal Server.
4. Follow the instructions in the Windows Components Wizard.
