Customers can log into their new image to customize using the local admin credentials emailed to the CAS Admin who created the image in CAS.

Next, log into the image, to be used in a collection or set of collections, and start to customize.

Disable IE Enhanced Security

In the Server Manager, disable the IE Enhanced Security to be able to download files on a new server.

Install Microsoft Remote Desktop Services

The quickest and easiest way to install the RD Session Host role is as follows.

NOTE:  This is only necessary if the customer plans to use that image for User Session Servers (USSs), or as Microsoft calls RDSH (Remote Desktop Session Host).  This is important, because customers are able to create images for app servers, etc.

In the Server Manager, go to Manage in the top right corner and click on Add Roles and Features.

Using the Add Roles and Features Wizard, click next on the Before you Begin screen and in the Installation Type select Role-based or feature-based installation and click Next.

Click Next again in the server selection and in the server roles page, scroll down to Remote Desktop Services, expand the rule and check the Remote Desktop Session Host role and click Next.

Click Next again in the features page and click Install on the Confirmation page to get the role installed

NOTE:  Please reboot the server after the installation is complete.

Windows Updates

While your image has been created from a current Google Cloud 'master' for the type of Windows Server selected, more recent Windows patches may need to be applied.  This can be done now or later on the VM Instance (typically, via WSUS).

Windows Installation Mode

NOTE:  Typically, this isn't a requirement anymore.   This was important on RDS for Windows 2008R2 & Windows 2012R2, but generally isn't required anymore.   However, there maybe the odd Windows-compatible application which might require this switch.

After the installation and reboot are done, customers can enter installation mode by launching a command prompt window as an admin.

Type change user /install and then exit out of install mode once you finish installing your applications with change user /execute

Installation Applications

Please install the applications for this image.    With very few exceptions, installing applications on a RDS-enabled server can be done exactly the same as a regular Windows server. 

Each image can have as many or as few applications as you want.   Remember, end-users won't be able to access until you grant them permission to each application via the itopia CAS Applications Module.

Be sure to. install any required licenses files.

Our Help Library contains a few helpful articles on application installs.   For example, this one for Microsoft Office365.

Complete Image Preparation in CAS Task Module

Once the image has been updated, then find the open Task in Task Module.    Hit 'Complete' to trigger CAS automation to prepare (i.e. sysprep) your new image to be used to deploy against new or existing VM instances in the Collection(s) of the customer's choice.
