Windows Server shuts down unexpectedly

In This Article:

Problem:

Some of the virtual servers in my infrastructure kept shutting down unexpectedly. All of these VMs are Windows Server 2016 evaluation (datacenter edition) and all my others VMs (Linux, Windows 7) wasn’t presenting these symptoms. Obviously, the problem related to the VM and the operating system itself.

Probably you have tried (or should try first) these solutions already here: Computer Shuts Down Randomly

Solution:

This is another simple solution but difficult to identify. I am using Windows Server 2016 evaluation in my test lab and didn’t notice that the evaluation period has expired. So, I need to rearm the server license to extend the trial period.

Windows will shut down on purpose, to remind you to activate the license! After solving this issue, the servers won’t shut down again, until you rearm the license again (You could do it up to 6 times). Of course, this is not for commercial purpose, only for testing labs.

Follow these steps:

  • Open Windows PowerShell
  • To check current license status, run  slmgr -dlv
  • To ream Windows license,  run slmgr -rearm.
  • Restart Windows, run Restart-Computer

Note: Curious thing, I had the same issue two years ago, and I totally forgot about it. That is why I consider important documenting everything, even though it could be a simple thing like this, the solution will change depending on your environment/situation.

Although the Raspberry Pi OS is designed and optimized for the Raspberry Pi module, it is possible to test and use it without its hardware, with VMware. This solution can be useful if you are a developer (or just a curious guy) and don't have a Raspberry Pi module with you

I was switching my storage array, so I migrated the VMs from that old datastore/storage to a new datastore/storage. The old datastore was shared by 3 ESXi hosts, no cluster. After migrating the VMs and unmount/delete the datastore, it was still presented in two of the ESXi hosts and was marked as inaccessible.

WinSCP VCSA

Unable to Access the VCSA 6.7 via WinSCP

One of the many and easiest ways to get the logs from the ESXi hosts and vCenter Server Appliance (VCSA), is accessing directly to the files directory using tools such as WinSCP, which helps to transfer the files between a local and a remote computer ( Ex. VCSA). I never have had issues with the ESXi hosts and WinSCP, however, trying to access the VCSA is a different story.
