Agent settings
Each RD Session Host in a RAS Farm has an RAS RD Session Host Agent installed through which it communicates with other Parallels RAS components. Use the Agent Settings tab to configure the agent.
To use default settings, select the Inherit default settings option. See Using default settings.
To configure the agent, set the options as described below.
Application session lingering
Disconnect active session after: Specifies the amount of time each session remains connected in the background after the user has closed a remote application. This option is used to avoid unnecessary reconnections with the server.
Logoff disconnected session after: This setting allows you to control how long it takes for a session to be logged off after it is marked as "disconnected".
Other settings
Port: Specifies a different remote desktop connection port number if a non-default port is configured on the server.
Max sessions: Specifies the maximum number of sessions.
Preferred Connection Broker: Select a Connection Broker to which the RD Session Host should connect. This is helpful when Site components are installed in multiple physical locations communicating through WAN. You can decrease network traffic by specifying a more appropriate Connection Broker.
Allow Client URL/Mail redirection
When a user tries to open a URL or an HTML Mailto link in a remote application, the link can be redirected to the client computer and open in a local default application (a web browser or email client) instead of an application on the remote host. To enable this functionality, select the option and click the Configure button. In the dialog that opens, select one of the following:
Replace Registered Application: This option uses an alternative method of redirecting a link. It replaces the default web browser and mail client with "dummy" apps on the remote server side. By doing so, it can intercept an attempt to open a link and redirect it to the client computer.
Support Windows Shell URL namespace objects: The Shell URL namespace objects support means that Parallels RAS can intercept actions in published applications that use the Shell namespace API to open links, which is a standard behavior in most applications. The ability to disable support for Shell URL namespace objects is for compatibility with older versions of Parallels RAS. You may disable this option if you want the behavior of an older version of Parallels RAS (RAS v16.2 or earlier).
Please note that you can configure a list of URLs that should never be redirected, even if the redirection is enabled. This can be done on the Farm > Site > Settings > URL Redirection tab. See more in Site settings.
Enable Drag and drop
Allows you to set how the drag and drop functionality works in Parallels Clients. To enable drag and drop, select the option, click the Configure button and then select from the following:
Server to client only: Drag and drop to a local application, but not in the opposite direction.
Client to server only: Drag and drop to a remote application only.
Bidirectional: Note that this option has changed since Parallels RAS 17.1. In the past, it was a checkbox that would enable or disable drag and drop which worked in the "Client to server only" mode. When upgrading from an older version of Parallels RAS, and if the checkbox was enabled, the "Client to server only" option is selected by default. If the option was disabled, the "Disabled" option will be set. You can change it to any of the new available options if you wish.
Note: At the time of this writing, the drag and drop functionality is only supported on Parallels Client for Windows and Parallels Client for Mac.
Allow 2XRemoteExec to send command to the client
Select this option to allow a process running on the server to instruct the client to deploy an application on the client side. Read more about 2XRemoteExec in the Using RemoteExec subsection at the end of this topic.
Use RemoteApp if available
Enable this option to allow use of remote apps for shell-related issues when an app is not displayed correctly. This feature is supported on the Parallels Client for Windows only.
Manage RDP transport protocol
Select the transport protocol that will be used for connections between Parallels Client and a server. To do this, select this option and click the Configure button.
Enable application monitoring
Enable or disable monitoring of applications on the server. Disabling application monitoring stops the WMI monitoring to reduce CPU usage on the server and network usage while transferring the information to RAS Connection Broker. If the option is enabled, the collected information will appear in a corresponding RAS report. If the option is disabled, the information from this server will be absent from a report.
Allow file transfer command (Web and Chrome clients)
Enables file transfer in a remote session. To enable file transfer, select this option and click the Configure button. For more information, see Configuring remote file transfer.
Enable drive redirection cache
Improves user experience by making file browsing and navigation on redirected drives much faster. For details, see Drive redirection cache.
Using 2XRemoteExec
2XRemoteExec is a feature that facilitates the servers ability to send commands to the client. This is done using the command line utility 2XRemoteExec.exe. Command line options include:
Command Line Parameter | Parameter Description |
| Used to run the 2XRemoteExec command in ‘silent’ mode. Without this parameter, the command will display pop up messages from the application. If you include the parameter, the messages will not be displayed. |
| Is used to specify the timeout until the application is started. Timeout must be a value between 5000ms and 30000ms. Note that the value inserted is in ‘ms’. If the timeout expires the command returns with an error. Please note that the application might still be started on the client. |
| Shows a help list of the parameters that 2XRemoteExec uses. |
| The Application that will be started on the client as prompted from the server. |
2XRemoteExec examples:
The following command displays a message box describing the parameters that can be used.
This command runs Notepad on the client.
In this example, the command opens the C:\readme.txt file in the Notepad on the client. No message is shown and 2XRemoteExec would wait for 6 seconds or until the application is started.
