How to Fix Horizon View Composer Upgrade error: There was an error identifying the validity of the server

Published by Rafael Moura on September 10, 2021

Working in a client other day I had a task to update an old VMware View environment from 7.0 to 7.12, a major gap indeed. It included the upgrade of vCenter Server, Connection Server and Composer.

After upgrading the View Composer I received the following message, which is expected, as the View Composer installer will re-generate the self-signed certificate and after successfully upgraded it’s just required that you accept and trust the new certificate.

However that was not what happened. Right after I got another error as follows:

There was an error identifying the validity of the server.

At this point I knew that something was wrong/dirty with ADAM database, anyway did my research I found many other issues related with UPN format, wrong Composer URL, NETBIOS/FQDN issues, etc. None of that was related with my issue.

After digging down the ADAM database and validating many settings I found where was it. The issue in this case was related with the certificate thumbprint value in ADAM settings and the connection server trust with the new View Composer certificate.

The value in the composer certificate thumbprint in the ADAM database was not reflecting the new certificate, and also after that, the Connection server started to complain about View Composer certificate not trusted, and not giving any option to proceed into the Horizon Console.

So here’s how I fixed the issue:

Log in to the View Composer Server, open MMC/Certificates/Computer and under Personal, extract the newly generated View Composer certificate.
Log in to the View Connection Server, open MMC/Certificates/Computer and under Trusted Root Certificates, import the extracted View Composer certificate previously.
Now it’s time to enter in the ADAM database, check the following VMware KB to make the connection with ADSI Edit.
Navigate to OU=Properties, OU=VirtualCenter, right-click on the CN=XXXX folder under it and select Properties.
Check the pae-SVISslCertificateThumbprint attribute, change that to reflect the new View Composer self-signed certificate thumbprint.
Restart the Composer and Connection Server services or servers.

At this point, navigate to Horizon Console and check the dashboard, the View Composer should be Green without any issue.

That’s it. It has been a long time since I worked with View Composer, as I couldn’t find the exact solution as my scenario, I made this post. 🙂

How to automate VMware DEM shares configuration using PowerShell

Published by Rafael Moura on July 5, 2021

Virtually anything can be done using PowerShell, if you have the proper time to understand the requirements, what you want to achieve and build the script. Whenever I have the opportunity I like to automate some tasks, basically to save some time and let me work on different things.

I had this script for a while, to easily configure VMware Dynamic Environment Manager during deployments and doing Lab, saving some time which could be spent on tougher and not time-consuming tasks.

I have only put together in a proper format adding some quick features to prompt the requirements.

So just run it and enjoy. 😉

Don’t forget to run the script as Administrator, it can be used in any SMB/CIFS/NFS solution, which your running account has administrative privileges.

Delivering great User Experience in an EUC Project

Published by Rafael Moura on June 11, 2021

Do it right on the first time

When an organization chooses to transition from common end-point physical computers, to Virtual Desktop Infrastructure (VDI), either on-premises or cloud-based, the IT department must do everything to minimize the risks and common issues that might happen. It is really common to architect the best possible design with an amazing hardware, a secure and reliable infrastructure, however all EUC projects at the end comes to the same point: “Are the users able to use it?” If you don’t know the answer you might not know how is the User eXperience for your clients.

The definition of User Experience (UX) is “A person’s emotions and attitudes about using a particular product, system or service. It includes the practical, experiential, affective, meaningful, and valuable aspects of human–computer interaction and product ownership”, which is basically how we interact with anything nowadays. When we open any application on a smartphone, when we use an ATM, while driving or watching YouTube, we’re interacting with many systems and each of them having a different user interface (UI) and also user experience (UX). The goal is to provide the best experience so that we, as users, enjoy using and without even realizing it, having them as good and reliable products.

It is not different than any EUC project, a successful project comes with a great user experience, the users will always define the project accomplishment, it doesn’t matter how amazing it looks like in the datacentre if the user experience is bad the users won’t buy it. To achieve a good user experience in this case, many steps and phases has to be planned, below I will list some key points to be taken in consideration in any project.

Proof of Concept

This phase is for IT department be able to test how the product and solution works, how would be integrated with the current environment, prerequisites and compatibility, and also possible to map use cases which was not yet defined. That phase usually is done as pre-sales activities.

Assessment

Every EUC project should start with a good assessment, it will give us an insight of end-user activity, to be better incorporated in the final approach. The assessment will also shows how many applications and what are most used, how is the performance of end users’ machine, which can be useful to set a virtual hardware for a Pilot, and many other performance metrics to help size and design the solution.

Latency, Quality and Usability

In order to deliver the best experience for the users, the virtual desktop should have an optimized image, there are a couple tools and procedures to achieve a good result on that, VMware and Citrix have good documented steps for optimization. After that we can monitor and test the usability and quality of that image, and also not least, be very cautious with latency, which can be a huge problem and affect the user experience, if it is not right sized. Many design approaches can be used to mitigate the latency, as cloud-based VDI, geolocation access on the nearest on-premises datacentre, virtual apps, etc. It will only depend on what the use cases should be achieved.

Pilot

In this phase an approach has been set, and the use cases are known, and many tests have been performed during the POC, now it’s time to see how everything works together and how end-users will utilize the newly solution. Usually a few users from different areas and expertise are selected to test and use the solution.

User Expectations and Feedback

That phase is highly important, as it will dictate whatever has to be fixed, changed or aligned in order to achieve users’ and project expectations. The feedback is also a great resource for the final production environment, a questionnaire should be sent together for each user, with questions regarding accessibility, usability, easiness, performance, etc.

At the end of the path we should have a good understanding of all aspects that must be considered during a EUC project, and the environment should be ready for production. It is not a difficult way, with the right tools and process everything is achievable. Always keep in mind that the user experience will dictate the value and reliability of the project and combining these key points will make the journey easier and satisfactory.
