You can create desktop assignments using the Assignments page or from the Getting Started wizard.


When you use the Blast Extreme or PCoIP display protocols, the correct video RAM value is dependent on the number of displays configured for end users and on the display resolution. The typical recommendation for a four monitor setup is 128 MB. For lower screen resolutions or fewer monitors, configure lower video RAM to save base memory for additional desktops.

When allocating RAM for the master VM, avoid choosing an overly conservative setting and take into account that insufficient RAM allocations can cause excessive Windows paging. Excessive Windows paging can generate I/O that causes significant performance degradations and increases storage I/O load. Configure video RAM in the master VM by editing the VM's hardware settings when it is powered off.

If you require the desktop image to be registered against an OU in Active Directory other than CN=Computers, you can use the General Settings page to configure that required OU as a default. See the Image Defaults Configuration option.

For more information about desktop assignments, see Types of Desktop Assignments. For more information about Active Directory, see Working with Nested Organizational Units.

Verify that you have at least one image listed on the Images page. You cannot create a desktop assignment without an image available in the system. See Convert a Desktop to an Image Using the New Image Workflow.


Open the New Assignment window by using one of these methods.

In the Getting Started wizard, click Desktop Assignment > Go for the Create New Desktop Assignment option.

If a desktop assignment has not been created yet, the button in the Getting Started wizard is New instead of Go.

From any location in the Administration Console, click Assign > New.


In the New Assignment dialog box, click Get Started in the Desktops selection.


Select the type of assignment to create, provide the required information to configure the desktop assignment, and click Next to advance to the next step in the wizard.


Windows 10 operating systems perform better with desktop models other than the Standard Desktop Model, because the other desktop models provide more memory. Even though you can use the Standard Desktop Model with Windows 10, as a best practice only do so for light workloads and basic applications.



Desktop Model

Select model from the drop-down list. After you select a desktop model, the Image text box is auto-populated.


Select your image.

Assignment Name

Type a unique name for the new assignment.

Default Protocol

Select a default display protocol, Blast or PCoIP.

Circumstances might occur that cause another protocol to be used instead of the default protocol. For example, the client device does not support the default protocol or the end user overrides the default protocol selection.

Preferred Client Type

Select the preferred client type used when end users launch desktops from the Workspace™ ONE™ portal, either a Horizon Client or a browser for HTML Access.


Horizon Client


Select the number of desktops required in the assignment.

Optionally configure the advanced properties.



VM Names

Name for all virtual machine names, or guest desktops in this assignment. When the guest desktops are deployed in the system, their names include the name specified here plus a number appended to it, such as win7-1, win7-2, and so on. This name must start with a letter and can contain only letters, dashes, and numbers. This value is prefilled based on the assignment name.

Computer OU

Active Directory (AD) Organizational Unit where the desktop VMs are to be located. For example, OU=NestedOrgName,OU=RootOrgName,DC=DomainComponent,DC=eng, and so on. The entries must be comma-separated with no spaces in between.

Run Once Script

(Optional) Location of scripts that you want run after system preparation completes.

Session Timeout Interval

The timeout value for floating and static desktop session pools. The default is seven days (10,080 minutes). The maximum value is 99,999 minutes, approximately 69 days.


If no user activity occurs before the timeout interval is reached, a message indicates that the user will be logged off if they do not click OK in the next 30 seconds. If the logoff occurs, any unsaved documents are lost.

If you are assigning a timeout value for dedicated desktops, you can specify the maximum value. If you have a large timeout interval set for floating desktops, the desktops do not reset as quickly if they are not in use. This configuration might result in the pool of available desktops running out, and users seeing failure messages.


(Optional) On the Active Directory Search page, start typing the name of a user or group from your Active Directory.


Select a user or group from the list.


(Optional) Search for and select additional users or groups, and click Next.


On the Summary page, confirm that the displayed information is correct and click Submit.

The system begins the process of creating the virtual desktops. On the Assignments page, the Status column reflects the current progress.


If the Administration Console does not automatically load the Assignments page, you can return to it by clicking the Assign icon.

To create additional desktop assignments, repeat Step 1 through Step 7.
