VMware vCenter – Download trusted root CA certificates

Welcome to my VMware vSphere series. In this section I will post different tips and tricks that will sort some common issues I have to tackle from time to time.

I recently experienced a problem when adding vCenter to my App Volumes setup. I figured this was related to certificates, as explained by VMware here: Unable to add vCenter to VMware App Volumes 3.0 This is also the cause when I experience problems uploading files to a datastore from vCenter.

To sort this issue I had to import my vCenter’s root CA certificates to my Windows Server hosting my App Volumes installation.

Start the web-browser directly to the vCenter GUI without appending port numbers or ‘vsphere-client’ extension. From this web-page I can download the trusted root CA certificates

I unzip the download.zip file, browse to certs\win and import the certificate to Trusted Root Certification Authorities. I select Local Machine as Store Location, Next.


I select Trusted Root Certification Authorities as Certificate Store, Next


I complete the Certificate Import Wizard, Finish.


If I only had one server that would need this root CA Certificate, this would be a viable solution, but in order to roll out this CA Certificate to other servers, I can use the GPO I created in my session about Windows CA, posted here: Microsoft Windows Server 2016 CA – Setup

I open Group Policy Management and edit my Root-CA GPO

I import my vCenter root CA Certificate to Trusted Root Certification Authorities

The Store Location is automatically Local Machine, Next


I browse and select my downloaded crt-file, Next


The Certificate Store looks correct, Next


I complete the Certificate Import Wizard, Finish.


Successful is always nice


The certificate is now present and ready for deployment

I now log back into the server with the certificate-problem and do a gpupdate /force in an administrative command prompt.


While this procedures fixes the issues in IE and Chrome, Firefox is another issue. The certificate has to be manually imported into Firefox.
