Before end users can access a remote desktop or published application, a Horizon administrator must configure certain pool and farm settings and install Horizon Agent on desktop virtual machines and RDS hosts in the data center.
The HTML Access client is a good alternative when Horizon Client software is not installed on the client system.
The Horizon Client software offers more features and better performance than the HTML Access client. For example, with the HTML Access client, some key combinations do not work in the remote desktop, but these key combinations do work with Horizon Client.
Verify that the Horizon components meet the system requirements for HTML Access. See System Requirements for HTML Access.
Verify that the HTML Access component is installed with Connection Server on the host or hosts and that the Windows firewalls on Connection Server instances and any security servers allow inbound traffic on TCP port 8443. See Preparing Connection Server and Security Servers.
If you use third-party firewalls, configure a rule to allow inbound traffic from Horizon servers to TCP port 22443 on desktop virtual machines and RDS hosts in the data center. See Firewall Rules for Client Web Browser Access.
Verify that the virtual machine you plan to use as a desktop source, or the RDS host that hosts published desktops and applications, has a supported operating system and VMware Tools installed. See System Requirements for HTML Access.
Become familiar with the procedures for creating pools and farms and entitling users. See the Setting Up Virtual Desktops in Horizon 7 and Setting Up Published Desktops and Applications in Horizon 7 documents.
To verify that the remote desktop or published application is accessible to end users, install Horizon Client for Windows on a client system. You can use Horizon Client for Windows to test the connection before you attempt to connect from a Web browser. For installation instructions, see the VMware Horizon Client for Windows Installation and Setup Guide document.
Verify that you have one of the supported browsers for accessing a remote desktop or published application. See System Requirements for HTML Access.
- For published desktops and applications, use Horizon Administrator to create or edit the farm and enable the Allow HTML Access to desktops and applications on this farm option in the farm settings.
- For virtual desktop pools, use Horizon Administrator to create or edit the desktop pool so that the pool can be used with HTML Access.
- Enable the HTML Access in the Desktop Pool settings.
- In the pool settings, verify that the Max resolution of any one monitor setting is 1920x1200 or higher.
- After the pools are created, recomposed, or upgraded to use Horizon Agent with the Allow HTML Access to desktops and applications on this farm or HTML Access option, use Horizon Client for Windows to connect to a remote desktop or published application.
With this step, before you attempt to use HTML Access, you verify that the pool is working correctly.
- Open a supported browser and enter a URL that points to your Connection Server instance.
You must include https in the URL.
- On the Web page that appears, click VMware Horizon HTML Access and log in as you do with Horizon Client for Windows.
- On the desktop and application selection page that appears, click an icon to connect.
You can now access a remote desktop or published application from a Web browser.
What to do next
For added security, if your security policies require that the HTML Access Agent on the remote desktop uses a TLS certificate from a certificate authority, see Configure HTML Access Agents to Use New TLS Certificates.
