Do not allow COM port redirection

Requirements: At least Microsoft Windows XP Terminal Services

Location: Computer Configuration\Windows Components\Terminal Services\Client/Server data redirection\


Description:
Disables the redirection of data to client COM ports from the server in Terminal Services sessions.

Use this setting to prevent users from redirecting data to COM port peripherals or mapping local COM ports while they are logged on to a terminal server. By default, Terminal Services allows users to redirect COM port data.

If you enable this setting, Terminal Services users cannot redirect server data to the local COM port.

If you disable this setting, COM port redirection is always allowed.

If you do not configure this setting, COM port redirection is not specified at the Group Policy level. However, an administrator can still disable local COM port redirection using the Terminal Services Configuration tool
