allows users to use their local files on a remote desktop within the terminal session, while "Printer Redirection" allows users to use their local printer within the terminal session as they would with a locally or network shared printer. "Port Redirection" allows applications running within the terminal session to access local serial and parallel ports directly, and "Audio" allows users to run an audio program on the remote desktop and have the sound redirected to their local computer. The clipboard can also be shared between the remote computer and the local computer. The RDP client in Windows XP can be upgraded to 7.0. The Remote Desktop Web Connection component of Internet Information Services 5.1 also allows remote desktop functionality over the web through an ActiveX control for Internet Explorer.
