Install VMware Tools Windows Server 2016 Core

I just completed my install of Windows Server 2016 Core as a guest in my VMware Lab. Now that this has been completed the next step is for me to install the VMware tools so that I can take advantage of various features; specifically, template deployment with customization options

About:VMware:Tools: VMware software tools enhance the performance of the guest operating system and improve the management of the virtual machine guests operating systems.

How to install:

  1. Select your VM from vCenter and select ‘Guest OS > Install VMware Tools
    This mounts the VMware CD Image containing the installation files
  2. Inside the guest machine type ‘powershell’
    This will drop you from the command shell to powershell prompt
  3. Next type the command Get-PSDrive
    This will return the drives attached to the system
  4. Change to the drive that the VMware tools are currently mounted
    In my case, this was drive letter “D”
  5. Issue the command .\setup64.exe to start the install process

    Note: issuing just setup.exe or setup64.exe will end in an error as Windows poweshell does not load commands such as this by default 
  6. Follow the steps of the VMware tools installer and restart when completed.



vSphere 6.5: OVF Import – The provided manifest file is invalid

Importing a template from vSphere 5.5 and importing to vSphere 6.5 the following error was encountered: The provided manifest file is invalidInvalid OVF checksum algorithm: SHA1

To get fix this error the following steps were taken:

Step 1 – is to extract your ova template (after all its only a zip)

You will notice 3 files once extracted

*.vmdk – is your disk containing all your data

*.ovf – is the configuration (also the file that we will edit)

*.mf – is a manifest containing a reference to the vmdk and ovf, also holding a SHA1 hash which ESXi will check for validation. This file needs to be deleted as we are making a change to the ovf and this will surely break that hash.

Example of what the contents of the .mf file looks like:

SHA1(template.ovf)= 908e804f140ffa58083b8bd154dace330b440c78
SHA1(template-disk1.vmdk)= 29c2d44d908d0207005360dabb58967f01a1

Step 2 – Delete the file with the *.mf extension. If this exists ESXi will attempt to validate and throw an error about the templates integrity being invalid. Once this has been deleted you can deploy your OVF Template.


Happy Importing

Saving Lives: American Heart Association! Please Donate

The following message is from my son: 

Hi, I’m Anthony and my friends and family call me AJ for short.  I’ve joined millions of others to help save lives alongside the American Heart Association!

At my school, I’m learning how I can help make a difference by raising lifesaving donations to help kids with heart disease.  I’m also learning about my own heart, and how to keep it healthy, by being active!

I’m excited to have the opportunity to help others, especially other kids who’s hearts don’t exactly work to their full potential.

Please help me make a difference

Thank you!

Important: Update Your Mozilla Web Browser to Firefox 58.0.1

Mozilla has released an important update for its Firefox web browser to patch a critical vulnerability that could allow remote attackers to execute malicious code on computers running an affected version of the browser.

Affected web browser versions include Firefox 56 (.0, .0.1, .0.2), 57 (.0, .0.1, .0.2, .0.3, .0.4), and 58 (.0). The vulnerability has been addressed in Firefox 58.0.1

Security fix

When using certain non-default security policies on Windows (for example with Windows Defender Exploit Protection or Webroot security products), Firefox 58.0 would fail to load pages (bug 1433065).

Reference link to 58.0 release notes

Known Issues of Security fix

  • Users running Firefox for Windows over a Remote Desktop Connection (RDP) may find that audio playback is disabled due to increased security restrictions.
  • Users running certain screen readers may experience performance issues and are advised to use Firefox ESR until performance issues are resolved in an upcoming future release.


According to a security advisory published by Cisco, Firefox 58.0.1 addresses an ‘arbitrary code execution’ flaw that originates due to ‘insufficient sanitization’ of HTML fragments in chrome-privileged documents (browser UI).


Hack Details:

Hackers could exploit this vulnerability (CVE-2018-5124) to run arbitrary code on the victim’s computer just by tricking them into accessing a link or ‘opening a file that submits malicious input to the affected software.’

The advisory states.

“A successful exploit could allow the attacker to execute arbitrary code with the privileges of the user. If the user has elevated privileges, the attacker could compromise the system completely,”

This could allow an attacker to install programs, create new accounts with full user rights, and view, change or delete data. However, if the application has been configured to have limited rights the impact is less on the system itself and should only impact the current session logged in.


Physical Fitness, Health & Leadership

Over many years I’ve come to learn from others and most importantly myself.  I recognize that leadership abilities have a common foundation made up of confidence, decisiveness, endurance as well as experience.  Another area I recognize are that of Physical Fitness, and Health that pull the aforementioned Leadership qualities together.


Team Entrainment 

Studies have shown that Entrainment in the biomusicological sense refers to the synchronization of organisms to an external perceived rhythm, such as music and dance such as foot tapping.

Individuals on a team over time, unconsciously mimic the behavior patterns of one-another and their source of leadership. If a leader is undisciplined or not punctual, their subordinates tend to follow suit. In the same way, a leader who does not make caring for one’s body and health a priority will have team members who will mirror this as well. There is a saying “Lead by Example” This is one that should not be deviated from.



Fit people are well known to be very productive and driven to complete goals. In addition to having the energy to take on new challenges, in addition to the willfulness to help others.

Some examples are:

  • Richard Branson, Founder of Virgin Group
  • Barack Obama, President of the USA
  • Mark Zuckerberg, CEO Facebook
  • Tim Cook, CEO Apple
  • Oprah Winfrey, Actress


Mental Health

Exercise has always been one of the best ways to help manage stress due to its ability to boosts endorphins. According to an article by the Mayo Clinic, exercise also reduces symptoms associated with anxiety and depression while improving sleeping patterns. 

Being in your best physical health will help improve your overall work ability, and this sets the stage for future advancement.


Creative Thinking

Being physically active assists in creative thinking. Studies suggest that even moderate levels of exercise increase cognitive abilities which aid in being a better decision maker. This goes the distance when develop business strategies, and “Thinking on one’s feet”.


Self Confidence

It’s been said recognized that Self-confidence is the fundamental basis from which leadership grows. Regular exercise boosts self-confidence. A person who regularly exercises possesses the creativity, goal orientation tendencies, mental stamina and productivity levels required to lead others.

A great leader pays attention to health. John F. Kennedy said, “Physical fitness is not only one of the most important keys to a healthy body, it is the basis of dynamic and creative intellectual activity.”

And with that I wish you all the best; current and future leaders alike.



“A great leader’s unique achievement is a human and social one which stems from his understanding of his fellow workers.”
