Remote Desktop Protocol
(redirected from Port 3389)

   Also found in: Wikipedia 0.03 sec.
(protocol)Remote Desktop Protocol - (RDP) A Microsoft protocol that provides remote display and input for Windows.

RDP's video driver renders display output by sending packets to the client which translates them into corresponding Microsoft Win32 graphics device interface API calls. Client mouse and keyboard events are redirected from the client to virtual keyboard and mouse drivers on the server.

RDP 4.0 was introduced with Windows NT Server 4.0, Terminal Server Edition. Windows 2000 Terminal Services included RDP 5.0. The Terminal Services Advanced Client (TSAC), an RDP client based on an ActiveX control, also supports RDP 5.0. RDP 5.0 provides enhanced performance over low-speed connections. Windows XP uses RDP 5.1 and includes Remote Desktop Web Connection, which is an updated version of the TSAC.

RDP extends the ITU T.120 protocols, allowing separate virtual channels for device communication and presentation data from the server, as well as encrypted mouse and keyboard data.

Compare: VNC.

You will need to have tcp port 3389 open on your firewall.
To get around this, tweak the settings on the router from port 3389 to the IP address of the computer on the internal network that uses Remote Assistance.
Using RDP alone requires opening port 3389 in the firewall, a practice which makes the system vulnerable.
