For the most part, PoE (Power over Ethernet) works perfectly with LLDP (Link Layer Discovery Protocol). I recently ran into a bizarre issue with a UniFi AP and an HPE Aruba switch where the AP would reboot under load. In this post, I will cover how I fixed it and everything I learned in this…
For the most part, 32-bit applications just work on the 64-bit version of Windows. However, I was curious about how it all works behind the scenes. In this post, I go down a rabbit hole exploring what makes 32-bit applications work on Windows 64-bit. WoW64 When Microsoft transitioned from 16-bit to 32-bit, they created a…
Cisco UCS can sometimes trigger a false positive alert of FFCH_ERROR_CARDS_ACCESS_ERROR on the FlexFlash controller, which typically has the fault ID of F1262. Depending on your setup, you should investigate the alarm appropriately. If, after your investigation, you determine that the fault is a false positive, the first step is to reset the FlexFlash controller.…
PowerShell is a wonderful tool built into Microsoft Windows. Both Windows and Windows Server come with PowerShell version 5.1 pre-installed. PowerShell version 5.1 was initially released in 2016. Since then, there have been many improvements to PowerShell. However, many of those improvements are only available in newer versions of PowerShell and aren’t always backported to…

With VMware vSphere, you can configure a native key provider that VMware vCenter fully manages. No external key provider is needed. The native key can even be used to encrypt your VMs. In this post, I will…
With Windows Server 2025, Microsoft is more in your face about sending your diagnostic data to them. I am okay with sending them the data if it helps make their products better. What I have a problem with is that the send diagnostic data to Microsoft screen is displayed on every first logon on each…
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…
There’s not a lot of official information about the prefs.txt file that the Omnissa Horizon client (formerly the VMware Horizon client) creates and uses. 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…
With Microsoft Windows installations, there’s a hidden user profile called Default. Anything in that user profile is copied directly to any new user account that logs into the computer. It is a template for each user who logs onto that system. The default user profile is located C:\Users\Default When a user logs into a Windows…
