The goal of this is to teach your co-workers to be more security conscious and LOCK THEIR PC when they walk away from their desk. Locking your PC stops unauthorized people from accessing your PC, viewing a document that has sensitive data, AND playing a prank such as THIS! This is especially important when you have access to sensitive data,…

I had this problem recently. No matter what browser I used, I couldn’t get past the login screen of the vSphere Web Client. My PC had upgraded to Flash Player 27.0.0.170 a few days ago. I attempted to uninstall this version and install a previous one with no success. But after doing some research, I found a KB Article from…

My company recently purchased some Dell Servers with ESXi installed to local SD cards. The issue we had was that the 8gb SD cards that came with the server and there wasn’t enough space on the cards for a scratch partition. We ordered the servers with a single 300gb HD in order to get the RAID controller, so we decided…

My InfoSec team came to us asking we disable anything older than TLS 1.2 and turn off RDP on our servers in the DMZ. We don’t allow RDP in the DMZ anyway, and they found that leaving RDP on when not using it poses a security risk. To do this, it involved multiple registry changes. With several servers to do…

Have you ever tried to delete a datastore and get an error saying the Datastore is in use? You browse the datastore and see nothing on it. The pre-checks when you unmount it all pass, yet you cannot delete it. We had this problem. VMware support directed us to delete the partition using the partedUtil command, but I didn’t like…

We recently ran into an issue where we had to update the Firmware & Bios on a bunch of Dell servers. As these are VMware hosts, we couldn’t just run the Dell System Update Utility, as I would on a normal Windows host. My coworker, @bspagna, and I decided to look at doing this via the iDRAC. Prerequisites: Dell Repository…

At my previous employer, we had a Dev/QA vSphere environment that was very over provisioned. The environment had lots of CPUReady issues with VMs having to wait for CPU time, which caused things to be slow, etc. We knew this but the application teams didn’t understand. I ended up writing a PowerCLI script to check the CPU overcommitment and sent…

I was thinking yesterday, I have a script that I run on a monthly basis to backup my vDS configs… Shouldn’t I also have something that does the same for my DRS rules? So, I wrote a script that I can schedule to run on a weekly/monthly basis to backup my DRS rules. I have multiple vCenter servers, so I…

As you may have seen, I really like a tool from a company called Devolutions called Remote Desktop Manager. I use it to manage my RDP sessions, Credentials, SSH sessions, as well as to manage my iDRAC/iLO connections. I also have it manage my connections to my VMware environments. For the environments that support the VI Client, I have those…
