An application server acts as the jump server between your bastion host and applications. To enable O&M access to Windows applications through Bastionhost, you must register a Windows host as an application server and deploy the USMDriver client on it. USMDriver is published as a RemoteApp program so that Bastionhost can proxy user access to Windows applications running on the server.
This guide covers both steps.
Prerequisites
A host is imported to your bastion host. For more information, see Add hosts.
Before you begin, make sure you have:
A host imported to your bastion host. For details, see Add hosts
Step 1/2: Add an application server
Log on to the Bastionhost console. In the top navigation bar, select the region where your bastion host resides.
In the bastion host list, find the bastion host you want to manage and click Manage.
In the left-side navigation pane, choose Assets > Applications.
On the Application Servers tab, click Add Application Server. In the dialog box, select the host you want to add as an application server and click Add.

Step 2/2: Deploy the application server
Log on to the Bastionhost console. In the top navigation bar, select the region where your bastion host resides.
In the bastion host list, find the bastion host you want to manage and click Manage.
In the left-side navigation pane, choose Assets > Applications.
On the Application Servers tab, find the application server you want to deploy and click Deploy in the Actions column.
In the Deploy Application Server panel, generate the deployment command as prompted. Then run the command in Windows PowerShell as an administrator.

The following figure shows the expected output after the command runs successfully.
ImportantThe host must be able to access the Internet. If the host cannot reach the Internet, the deployment package cannot be downloaded and the command will fail.
Publish USMDriver as a RemoteApp program on the application server. The following example shows how to publish USMDriver RemoteApp on a host running Windows Server 2019.
In Server Manager, navigate to Remote Desktop Services > Collections > QuickSessionCollection and choose TASKS > Publish RemoteApp Programs.

In the Select RemoteApp programs dialog box, select USMDriver and click Next.
ImportantIf USMDriver does not appear in the list, add it manually. The default path is
C:\Program Files (x86)\USMDriver\USMDriver.exe.
Confirm that the USMDriver RemoteApp program is selected and click Publish.
Right-click USMDriver and click Edit Properties.

On the Parameters tab, select Allow any command-line parameters and click Apply.
