Let say you are running Exchange Server 2010 installed on Windows Server 2008 R2 SP1 x64(bit), and when you remotely open Outlook Web Access (OWA to the Exchange Server) in your Google Chrome web browser it alerts you that the installed SSL certificate is insecure. When you check the detail about the SSL certificate, the web browser is letting you know that the configured SSL protocols on the server are deprecated.

As the Administrator, you first run an SSL Test and analysis of your webserver using the Qualys SSL Labs' SSL test from here: https://ssllabs.com/ssltest/ in order to analyze which Secure Socket Layer (SSL) and Transport Layer Security (TLS) protocols are available, enabled and/or set as default within the registry of your Server. Before inputting your server's web address to run these tests and to obtain a report, it is recommended for the sake of your webserver's privacy that you check the checkbox next to: “Do not show the results on the boards.”

This update provides support for Transport Layer Security (TLS) 1.1 and TLS 1.2 in Windows Server 2012, Windows 7 Service Pack 1 (SP1), and Windows Server 2008 R2 SP1.

To obtain the stand-alone package for this update, go to the Microsoft Update Catalog website here: https://www.catalog.update.microsoft.com/search.aspx?q=kb3140245 and download and install the catalog update applicable to your server, such as “Update for Windows Server 2008 R2 x64 Edition (KB3140245).

Prerequisites for your server: To apply this update, you Windows Server 2008 R2 must have installed Service Pack 1 (SP1) for Windows 7 or Windows Server 2008 R2.

To understand why this update is or may be necessary, please review this Microsoft Support article: https://support.microsoft.com/en-us/topic/update-to-enable-tls-1-1-and-tls-1-2-as-default-secure-protocols-in-winhttp-in-windows-c4bd73d2-31d7-761e-0178-11268bb10392

At the top of the Window's registry tree, select “Computer” right click on “Computer” and left click “Export” and then supply a name to the registry backup file, and save this exported copy of your registry in a folder (directory) where in the future you can locate and import this registry backup if you happen to make a huge mistake while editing the Windows registry.

In the registry, browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols

Create a new Key named TLS 1.2. How? Right click on the Protocols key, and left click on 'New' and left click on 'Key' and input the name of the new key as being TLS 1.2 and press enter or click on any white space to set the name of the key.

In the same manner, create two new subkeys each under the key named TLS 1.2 and name these new subkeys as Client and Server respectively.

In the Registry, browse to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client and Create a new DWORD value named: DisabledByDefault and Set the value to: 0 (hexadecimal)

How? Right click on the Client subkey, and left click on new - DWord 32bit and name the Dword as DisabledByDefault and right click the new Dword that is named DisabledByDefault and select 'Modify' and set the value as 0 with the radio button for hexadecimal selected.

Also, under the Client subkey, create a new DWORD value named: Enabled and set the value to 1 (hexadecimal).

Now, in the Registry, browse to the new subkey named Server located at: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server

In the same manner under the Server subkey, create a new DWORD (32-bit) value named: DisabledByDefault and set its value in hexadecimal to: 0

In the same manner under the Server subkey, create a new DWORD (32-bit) value named: Enabled and set its value to 1
