How to Enable TLS 1.2 on Windows Server 2008 R2 and IIS 7.5

Written by , Updated on March 23, 2018

Nowadays there is an SSL vulnerability called POODLE discovered by Google team in SSLv3 protocol. So uses of SSLv3 is not secure to use. Now it’s recommended using TLS 1.2. This article will help you enable TLS security in Windows Server 2008 R2 or later versions by editing registry.

Step 1 – Backup Registry Settings

We strongly recommend taking a backup of the registry before making any changes. Use below link to find steps to how to export registry values.

Step 2 – Enable TLS 1.2 on Windows

You have two options to enable TLS version on your system.

Option 1 – Merge Resistry File

Download the Enable-TLS12-Windows.reg and Enable-TLS12-TLS11-Windows.reg files on your Windows system. Now right click on file and click Merge.

Option 2 – Manually Update Registry

You can do this by directly editing registry file manually.

2.1 Open registry on your server by running ‘regedit‘ in run window and navigate to below location.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols

2.2 Add the TLS 1.1 and TLS 1.2 keys under Protocols. It will looks like directories.

TLS-1

2.3 Now create two keys Client and Server under both TLS keys.

2.4 Now create the DWORD Values under Server and Client key as following

  DisabledByDefault [Value = 0]
  Enabled [Value = 1]

TLS-2

Step 3 – Disable TLS and SSL Older Versions

3.1 Open registry on your server by running ‘regedit’ in run window and navigate to below location.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols

3.2 Now change DWORD Values under Server and Client under TLS 1.0, SSL 3.0 and Older SSL version keys.

  DisabledByDefault [Value = 0]
  Enabled  [Value = 0]

After making all above setting reboot your server.

    Can’t get this working on Server 2008 R2.
    Have tried manually, scripted and using Nartac’s IISCrypto, but even after a reboot, my SSL Report fails with “Assessment failed: No secure protocols supported” and I can’t connect to any of the web pages on the server.

    Have repeatedly checked the registry keys so that SSL 2.0, SSL 3.0 and TLS 1.0 are disabled, TLS 1.1 and TLS 1.2 are enabled.

    I noticed when I used IISCrypto though, that the values for TLS1.1 and TLS1.2 wehere configured as hex 0xffffffff or decimal value 4294967295. It is not configured as 1 as per my registry values:

    I’m guessing the value just needs to be a positive integer. But configuring the “Enabled” DWORD as decimal 1 didn’t make any difference anyway. Trying to figure out why it’s not working though. Any thoughts?

    Here’s a PowerShell script I wrote that does it too.

    $SSLTLS = “HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols”
    $Types = “Client” , “Server”
    $SK2V = ( 0..7 | % { 0 } ) + ( 8..9 | % { 1 } )

    $Protocols = @( 2..3 | % { “SSL $_.0” } ) + @( 0..2 | % { “TLS 1.$_” } )
    $Protocols | % `
    {
    $Path = “$SSLTLS\$_”
    If ( ( Test-Path $Path ) -ne $True ) { NI -Path “$SSLTLS” -Name “$_” }
    $Types | % { If ( ( Test-Path “$Path\$_” ) -ne $True ) { NI -Path “$Path” -Name “$_” } }
    }

    $Path = @( $Protocols | % { “$SSLTLS\$_\Client” ; “$SSLTLS\$_\Server” } )

    0..( $Path.Count – 1 ) | % `

    SSL Certificate Incorrect Configuration – INTG Server Accepts SYST client Certificate and returns 200 response

    We have developed a Web API application and we are using Mutual TLS V1.2 for Authentication. We have two servers (X and Y) in INTG Environment and also we have a load balancer. Server X and Y are accessed via load balancer server.

    I have hit one of the Web Api Get request URL by selecting the Client certificate in Chrome browser if the request goes to server Y and if I pass a valid INTG client certificate it’s working fine and If I pass invalid client certificate or other environment(SYST) certificate it throws 401 UnAuthorized. This is the correct behavior and it is working fine in Y.

    But in the Server X if I pass invalid certificate it’s throwing 401 Unauthorized but if I pass SYST Client Certificate it’s working and I am getting the 200 response. It should not accept SYST client certificate in INTG Environment and it should throw 401 UnAuthorized but it is accepting it and I am getting 200 Response.

    I verified both the server configurations everything appears same and I don’t see any difference.

    I identified this issue by stopping the site alternatively in both the servers.

    We are using “iisClientCertificateAuthenticationMapping” and in that we have set the “manyToOneCertificateMappingsEnabled” as False and “oneToOneCertificateMapingsEnabled” as True and for “oneToOneMappings” I have set the userName, password and certificate(base64string).

    Can you guys please let me know what are the possible reasons for the X server’s incorrect behavior.

    INTG SERVERS:

    Server X
    Server Y

    The notion that setting the Enable key to 0x00000001 is absolutely incorrect. To activate the TLS setting, the Enable key must be set to 0xffffffff. This is the only way I could get it to function correctly

    Ugo Meex, you have made my day! This is the official Golden TIP of the month! Took me 4 days to investigate why Windows 10 1511 (fall update) clients couldn’t connect to our RADIUS Wi-Fi network anymore. With your tool, it took me 3 mouse clicks and 1 reboot…. everything solved.

    It should be made very clear that this works for Server 2008 R2 and later, but *will not* work for “Server 2008” (which also means, it will not work for SBS 2008 either). Unfortunately, the article title is misleading; TLS 1.1/1.2 are not supported prior to Server 2008R2 and SBS 2011 on the server side.

    While this article is certainly very useful, in a windows environment it would be far easier to use the IISCrypto tool by Nartac Software. It’s small, it’s free, it’s easy to use.

    Rather than having to read and edit the registry, this utility gives you a GUI to make these changes.
    It also offers 1 click config for: Best practices, PCI and FIPS 140-2
    https://www.nartac.com/Products/IISCrypto/

    Same result, but faster and certainly easier. 🙂

      Your script does the exact same thing as the manual instructions listed in this article, how is it incomplete?

        for ssl 2.0 you have DisabledByDefault [Value = 0] but the script does “DisabledByDefault”=dword:00000001

          I ran this script and it did nothing. I have Server 2008 R2. FYI, I do not have TSL 1.0 and 2.0 but if I am not wrong this script should create entries for these.
          Thanks

    This will not work on Windows Server 2008 SP2 but does work on Windows Server 2008 R2.
    TLS 1.1 and TLS 1.2 does not seem to come with Windows Server 2008 SP2, a bit of an issue for me.

    Hi Rahul, thanks for this. Shouldn’t your Step 3.2 be: DisabledByDefault [Value = 1] rather than [Value = 0] to disable by default?

    Will this instruction to add TLS 1.1 and TLS 1.2 work on Windows 2008 Standard version?
