Xendesktop 7.5 – cannot connect to the vcenter server due to a certificate error

This is a repeat of one of my previous blog. The intention to re-write the blog is for following reasons:
The issue still persists with the latest version of XenDesktop Edition i.e. 7.5 with Windows Server 2012 R2 environment.
The error report has been improved in the latest version. The error clearly states where the problem lies, which is good. But I would like to see it as a pre-requisite checklist when you run the XenDesktop installer at the beginning. 
Lastly, to make you familiar with the new look/options and error of the certificate issue.
After installing XenDesktop 7.5 (Studio and other components) on the server (usually known as controller, broker server), the first step in the setup/configuration phase is Adding a Site i.e. ‘Site Setup’.
Once the Site Setup window opens, follow the instructions, fill the appropriate values, hit Next and you reach the ‘Connection’ wizard. You select Connection Type ‘VMware vSphere’ and you see the fields specific to adding vSphere hosting infrastructure for your X A/X D environment.
When you enter the Connection address as https://<vCenterServerIPorFQDNaddress>/sdk followed by your vCenter Server Administrative Username/password (the one that you use to login to your vCenter environment using vSphere Client or vSphere Web Client, you may encounter the following error:
This error occurs because the XenDesktop Controller (broker) server does not authenticate/allow the vCenter Server certificate (usually when vCenter Server is using default self-signed certificate). 
To resolve, you need to export the vCenter Server certificate and import it into the Trusted People/Local Machine of the XenDesktop Controller server. Two step process:
1) Export vCenter Server Certifiate
2) Import vCenter Server Certificate into X D controller certificate store
1) Export vCenter Server Certifiate
On the X D controller server, open the vCenter Server URL in a web browser. You’ll get the Certificate Warning page. On the address bar, depdending on the browser you’re using, below is example from chrome/IE:
If IE, click on View Certificates and if Chrome, click on hyperlink Certificate information, you’ll see the certificate window from where you can export the certificate. (Note: Sometimes you may see the Install Certificate button is missing. In that case, just try opening the vCenter Server URL using browser from a different server (2008 ) or a client machine (Windows 7) instead of the X D broker/controller server)
Click on Install Certificate

Right-click the certificate > All Tasks > Export…
 Click Next
 Leave the default format (DER encoded / .CER), click Next
 Browse to a location from where the X D Controller server has access to import into its certificate store.
 Click Finish
2) Import vCenter Server Certificate into X D controller certificate store
 Once the vCenter Server certificate is successfully exported on a shared location. Go back to your XenDesktop controller server. Go to run > type mmc > hit Enter > Add the Certificate Console using the Add/remove Snap-in option. Expand the Certificates console tree > Right-click Trusted People > All Tasks > Import…

 Ensure Local Machine is selected, click Next
 Browse & Select to the shared location where you saved the vCenter Server certificate, Click Next
 Select the Option “Place all certificates in the following store”, Navigate & Select Trusted People, Click Next
 Ensure all ok and click Finish
 You should see the following message which pops up in 1-2 seconds.
Verify it works:
Go to the Xendesktop studio, type in all the vCenter Server information under Hosting Connection wizard. Click Next and you should see the following screens which means it worked.

  1. You can cut this down to two simple steps.
    1)On the DDC, go to https://vsphereserverhostname, click “continue anyway” and then “certificate error” will appear on the address bar. click that. You get a window showing the certificate.
    2)Click “Install Certificate” and choose “Local computer” and select the “trusted people” location in the datastore as to where to put it.

    You’re done.
