At the very core of Omnissa Horizon is an ADAM (Active Directory Application Mode) LDAP (Lightweight Directory Access Protocol) database. Even though Horizon servers are typically domain-joined, they still maintain their own ADAM LDAP database for all the configurations in Horizon. It’s a good idea to back up the ADAM LDAP database as it can…
There are a few ways to preload the Omnissa Horizon client (formerly the VMware Horizon client) with a default Horizon Connection Server. One method is to deploy the Horizon prefs.txt file with the Horizon connection server. For more information about the prefs.txt file method, my blog post, Omnissa Horizon Client prefs.txt, goes into detail. Another…

I’ve figured out that the prefs.txt text file is in XML format and is generated by the Horizon client, usually once the user changes a setting in the Horizon client. It…

In this post, I will detail what happens when an Omnissa Horizon Term License expires and the messaging that administrators and end users will see. Starting with Omnissa…
I recently encountered a strange issue with Omnissa Horizon (formerly VMware Horizon) that resulted in a black screen presenting to the VDI users when they logged in. When you search for this issue, you will find a lot of information about various solutions to the blank screen issue. However, none of them solved the problem…
Installing an SSL/TLS certificate on the Omnissa Horizon Connection Server (formerly the VMware Horizon Connection Server) is a common task. The whole process may feel daunting if you’ve never installed a certificate on the Horizon Connection Server. Omnissa Horizon has had a few names, and some of those old names are still present at its…
Installing your own certificate is one of the first things you’ll need to do when setting up the Omnissa Unified Access Gateway appliance (formerly the VMware Unified Access Gateway appliance). In this post, I will detail step-by-step how to install a certificate on the VMware UAG. Prerequisites The Process
You usually want to connect Omnissa Horizon (formerly VMware Horizon) directly to VMware vCenter, but it can make sense to leave them disconnected from each other in some situations. In this post, I’ll show you step-by-step how to install the VMware Horizon Agent without using the VMware vCenter integration. You can do this on persistent…
I’m a big fan of using copy paste as it helps me reduce typos and allows me to paste links or other information quickly between systems. Previously I wrote a post that covers how to enable copy paste with VMRC (VMware Remote Console) however that’s not super useful for the users that are using Omnissa…
In this post, I will detail step-by-step how to install the Omnissa Horizon (formerly VMware Horizon) GPO templates. Technically speaking you can fully use Horizon without any of the GPO templates however there are a lot of useful settings in them that you can configure. Before installing the Horizon GPO templates I recommend you create…
