WARNING: Request-CSCertificate failed – Lync 2013

Installing Lync 2013 Server or Skype for Business – Getting error “Warning: Request-CSCertificate failed”

When deploying Skype for Business / Lync server in my lab, i got an error “Warning: Request-CSCertificate failed” in the step where we have to request for a certificate.


Login to Certificate Authority (CA) Server :

To troubleshoot and resolve the issue, I simply logged into my CA server and made the following changes:

  • Login to Windows CA Server
  • Go to Run and type “certsrv.msc”
  • Right Click CA server and click on Propertiesuccollabing.com
  • Click on Security tab
  • Select the Username that you are using while installing the Lync Server. I was using Administrator in my lab server and hence i selected Domain\Administratoruccollabing.com 
  • Checkbox “Request Certificates” and click on Apply and OK.
  • Re-run the “Request” certificate wizard and the issue should be resolved.

That’s all, i hope this helps!
