title: How to update the validity period of an existing CA template programatically or using command-line program
body: <p>I'm looking for a way to update the Validity period of an existing CA Template, do you know if this is possible using certutil, any other command or programatically with Powershell or C#.</p>
  
  <p>The CA is running on Windows Server 2008 R2.  </p>
  
  <p>My goal is run a script on a daily basis to update the validity period for a specific template in order that any request enrolled using that template expires on a specific date, let's say Dec 31st, 2016.</p>
  
  <p>Thanks,</p>
