TLS, fully formed as Transport Layer Security protocol provides secure data exchange (thereby avoiding eavesdropping) over network needed for web applications, emailing & web browsers. It’s a true successor to SSL and now widely used owing to a vulnerability called POODLE found in SSLv3 protocol.
Windows 2008 R2 server doesn’t come with this feature enabled by default, but has to be done in the following way.
WORD OF CAUTION: We highly advise you to fully backup the Windows registry for safer side just in case something goes wrong.
Step 1. Run ‘regedit’ command in run window
Step 2. Simply right click on the Protocols folder, from the drop-down menu select New and then Key . Now rename the newly created folder as TLS 1.2.
Step 3. Now create two keys Client and Server under both TLS keys.
Step 4. Now create the DWORD Values under Server and Client key as given below.
This is how you do it!
