Mstsc 命令参考
Updated: September 28, 2007

Creates connections to terminal servers or other remote computers, edits an existing Remote Desktop Connection (.rdp) configuration file, and migrates legacy connection files that were created with Client Connection Manager to new .rdp connection files.

For examples of how to use this command, see Examples.

Syntax

mstsc.exe [<Connection File>] [/v:<Server>[:<Port>]] [/admin] [/f] [/w:<Width> /h:<Height>] [/public] [/span]

mstsc.exe /edit <Connection File>

mstsc.exe /migrate

Parameters
 
Parameter  Description  
<Connection File>
 Specifies the name of an .rdp file for the connection.
 
/v:<Server[:<Port>]
 Specifies the remote computer and, optionally, the port number to which you want to connect.
 
/admin
 Connects you to a session for administering the server.
 
/f
 Starts Remote Desktop Connection in full-screen mode.
 
/w:<Width>
 Specifies the width of the Remote Desktop window.
 
/h:<Height>
 Specifies the height of the Remote Desktop window.
 
/public
 Runs Remote Desktop in public mode. In public mode, passwords and bitmaps are not cached.
 
/span
 Matches the Remote Desktop width and height with the local virtual desktop, spanning across multiple monitors if necessary.
 
/edit <Connection File>
 Opens the specified .rdp file for editing.
 
/migrate
 Migrates legacy connection files that were created with Client Connection Manager to new .rdp connection files.
 
/?

Remarks
Default.rdp is stored for each user as a hidden file in the user's Documents folder. User created .rdp files are saved by default in the user's Documents folder but can be saved anywhere.

To span across monitors, the monitors must use the same resolution and must be aligned horizontally (that is, side by side). There is currently no support for spanning multiple monitors vertically on the client system.

Examples
To connect to a session in full-screen mode, type:

mstsc /f
To open a file called filename.rdp for editing, type:

mstsc /edit filename.rdp
