PoC Guide: Remote PC Access with Citrix DaaS

Overview

This Proof of Concept guide is designed to help you quickly configure Citrix DaaS to include Remote PC Access in your environment. At the end of this Proof of Concept guide you will be able to give users who are working remotely access to the on-premises physical desktops using Citrix DaaS. You will be able to let your users access their on-premises workstations on any device of their choice without having to connect over a VPN.

Conceptual Architecture

Scope

In this Proof of Concept guide, you will experience the role of a Citrix administrator and you will create a connection between your organization’s on-premises deployment of physical desktops and Citrix Daas. You will provide access to those on-premises workstations to an end user with Citrix DaaS using Citrix Workspace.

This guide will showcase how to perform the following actions:

1. Create a Citrix Cloud account (if you don’t have one already)
2. Obtain a Citrix DaaS account
3. Create a new Resource Location (your office) and install the Citrix Cloud Connectors in it
4. Install Citrix Virtual Delivery Agent on the Remote PC Access hosts
5. Create a Machine Catalog in Citrix DaaS
6. Create a Delivery Group
7. Launch a session from Citrix Workspace

Prerequisites

Host machine requirements

The in-office workstations that your users must connect to are Windows single-session operating system machines, and are joined to a Windows Active Directory (AD) domain.

Citrix Cloud Connector

To install the Citrix Cloud Connectors in your environment, you require (at least two) Windows Server 2012 R2 or later server machines/VMs. You require static IPs for these two machines. Windows installation and domain join of these machines must have been done in advance. The system requirements for the Cloud Connectors are here. Review the guidance on the cloud connector installation here. The machine the Citrix Cloud Connector runs on must have network access to all the physical machines that are to be made available on the internet via the Citrix Workspace.

Some requirements Citrix Cloud Connector installation (installer performs checks for these) are:

The Citrix Cloud Connector machine must have outbound Internet access on port 443, and port 80 to only *.digicert.com. The port 80 requirement is for X.509 certificate validation. See more info here

Microsoft .NET Framework 4.7.2 or later must be pre-installed on the machine

Time on the machine must be synced with UTC

This guide provides detailed instructions on how to configure your environment including office workstations, connecting your on-premises setup up to Citrix Cloud. As a Citrix Cloud administrator, you enable your users to connect to their office workstations remote with Citrix DaaS.

Create a Citrix Cloud Account

If you are an existing Citrix Cloud customer, skip to the next section: Request Citrix DaaS Trial. Ensure that you have an active Citrix Cloud account. If your account has expired, contact your account manager to enable it.

If you need to sign up for a new Citrix Cloud account please follow the step by step instructions here: Signing up for Citrix Cloud

Request a Citrix DaaS Trial

1. Sign in to your Citrix Cloud account
2. From the management console, select Request Trial for the service you wish to trial, in this case Citrix DaaS.

Note For some services you must reqwuest a demo from a Citrix sales representative before you can try out the service. Requesting a demo allows you to discuss your organization’s cloud service needs with a Citrix sales representative. Also, the sales representative ensures you have all the information needed to use the service successfully.

When your trial is approved and ready to use, Citrix will send you an email notification.
