If you are using a Windows Server 2008 R2, you may encounter some issues when trying to connect to certain websites. One of the reasons is because Windows Server 2008 R2, by default, may not have the TLS 1.1 protocol enabled. The Transport Layer Security (TLS) protocol is a security protocol that encrypts communication between a client and a server over the internet. If you do not have this protocol enabled, it may result in an inability to connect to some websites, leaving your server vulnerable to attacks.
But don’t worry, enabling TLS 1.1 on your Windows Server 2008 R2 is not a complicated task. In this blog post, we will guide you through the process of enabling TLS 1.1 on your Windows Server 2008 R2. We have compiled a few methods that can help you to get this job done without breaking a sweat.

What’s Needed
Before we proceed to the methods, there are a few things you need to prepare.
1. Administrator access
You must have administrator access to the server to enable the TLS 1.1 protocol.
2. Knowledge of registry editing
The methods we will discuss require editing the registry, so it is important to know how to do this safely.
3. Safety measures
It is essential to create a backup and restore point for the registry before editing anything to avoid any possible damage to your system.
What requires your focus?
Enabling TLS 1.1 on Windows Server 2008 R2 involves editing your server’s registry. You need to be very cautious while making changes to your registry, as even a small mistake can cause serious issues. Handle your registry with care, and make sure you follow the methods correctly.
Methods to Enable TLS 1.1
We have compiled a few methods that can help you enable the TLS 1.1 protocol on Windows Server 2008 R2. Please note that these methods involve editing the registry, so be very careful and follow the instructions carefully.
Method 1: Editing the Registry Editor to Enable TLS 1.1
1. Press the Win+R keys on your keyboard to open the run dialog box.
2. Type regedit in the search box and press Enter.
3. Navigate to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\
TLS 1.1
4. Right-click on the TLS 1.1 key and select New > Key.
5. Type the word "Client" and press Enter.
6. Right-click on the Client key and select New > DWORD (32-bit) Value.
7. Type the word "DisabledByDefault" and press Enter.
8. Double-click the "DisabledByDefault" value and set the value data to 0.
9. Right-click on the Client key and Select New > DWORD (32-bit) Value.
10. Type the word "Enabled" and press Enter.
11. Double-click the "Enabled" value and set the value data to 1.
12. Close the registry editor, and restart your server.
Pros:
– This method is relatively simple and easy to follow.
– You only need to modify one registry key, and it is easy to undo any changes if there are any issues.
Cons:
– Modifying your registry can be dangerous and cause serious problems if done incorrectly.
– Any errors made while editing the registry could cause serious issues with your server.
Method 2: Using the Group Policy Editor to Enable TLS 1.1
1. Press the Win+R keys on your keyboard to open the run dialog box.
2. Type gpedit.msc in the search box and press Enter.
3. Navigate to the following location:
Computer Configuration > Administrative Templates > Windows Components > Internet Explorer > Internet Control Panel > Advanced Page
4. In the right pane, locate the option "Turn off encryption support" and double-click it.
5. Set the option to "Disabled" and check the box "Use TLS 1.1."
6. Click "Apply" and then "OK."
7. Restart your server.
Pros:
– Group Policy is a powerful tool that can be used to control and manage settings for a large number of computers.
– Using Group Policy to modify the TLS 1.1 settings is a centralized process that makes it easy to apply these changes across an entire network.
Cons:
– This method requires you to have active directory infrastructure in place.
– If you are not familiar with using Group Policy, it can be a bit difficult to set up and configure correctly.
Method 3: Enabling TLS 1.1 through Command Prompt
1. Press the Win+R keys on your keyboard to open the run dialog box.
2. Type cmd in the search box and press Enter.
3. Type the following command and press Enter:
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Client" /v "DisabledByDefault" /t REG_DWORD /d 00000000 /f
4. Type the following command and press Enter:
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Client" /v "Enabled" /t REG_DWORD /d 00000001 /f
5. Restart your server.
Pros:
– This method is very quick and easy to execute.
– It does not require knowledge of how to use the registry editor.
Cons:
– This method only applies to the client-side of TLS and may not resolve all issues you may encounter.
– If you make any typos when entering the commands, it can cause errors in the registry.
Why Can’t I Enable TLS 1.1?
There are a few reasons why you might not be able to enable the TLS 1.1 protocol on your Windows Server 2008 R2. Here are some possible reasons:
1. Outdated Operating System
If your server is outdated and does not have the latest updates installed, enabling the TLS 1.1 protocol could cause compatibility issues.
2. Firewall Restrictions
Your firewall settings could block the TLS 1.1 protocol from being enabled.
3. Security Settings
If your server is set to the highest security levels, enabling the TLS 1.1 protocol may not be allowed.
Fixes:
1. Make sure that your server is updated with the latest security updates before enabling the TLS 1.1 protocol.
2. Double-check your firewall settings to ensure that they allow the TLS 1.1 protocol.
3. Lower the security settings on your server to allow the TLS 1.1 protocol to be enabled.
Implications and Recommendations
Transport Layer Security (TLS) protocol is essential in ensuring that communication between servers and clients over the internet remains secure. Enabling TLS 1.1 on your Windows Server 2008 R2 is a good way to enhance your server’s security and make sure that you can connect to all websites with ease.
However, it is crucial to handle your registry with care. Editing the registry can be dangerous if done incorrectly, so follow the steps carefully or get help from an expert.
It is also crucial to keep your Windows Server 2008 R2 up to date to ensure your server’s security is not compromised.
