title: How to enable server side SSL3.0, TSL1 on Windows server 2016 (IIS 10)?
body: <p>I know Windows Server 2016 by default disabled SSL3.0 and TSL1 for IIS 10 service.</p>
  
  <p>My question is how to enable them?</p>
  
  <p>I followed the steps in the thread
  <a href="https://social.technet.microsoft.com/Forums/windowsserver/en-US/a6f6fa60-03fb-49f6-b356-de4aa7633738/how-to-disable-tls-and-enable-ssl30-on-iis?forum=winserverNIS" rel="nofollow noreferrer">https://social.technet.microsoft.com/Forums/windowsserver/en-US/a6f6fa60-03fb-49f6-b356-de4aa7633738/how-to-disable-tls-and-enable-ssl30-on-iis?forum=winserverNIS</a></p>
  
  <p>But, it still doesn't work for me.
  SSL3.0 and TLS1 is not enabled at the server side.</p>
  
  <p>I am trying to fix the issue on following thread. But, I don't want toto change the client code. I want to figure out a way to allow Windows Server 2016 to allow SSL3.0 and TLS1.
