Mediasite Recorder Configuration (v7.3.3)

For a Mediasite deployment to be fully compliant with TLS 1.2, the Recorders must be running Mediasite Recorder software 7.3.3+ and configured to use TLS 1.2.

It’s recommended that you begin with enabling TLS 1.0, 1.1 and 1.2. This will offer the highest level of flexibility with the other component of Mediasite. Once you have verified that all of Mediasite functions properly over https, then you can come back and lock down the recorders to use TLS 1.2 only.

To enable TLS 1.2, please follow these steps:

Upgrade to Recorder 7.3.3 Build 3002

Ensure that your Recorder is running the latest version of Recorder software. If it doesn’t support Recorder 7.5 or above, please make sure you upgrade to the latest version of 7.3.3.

Please note, Recorders must be restored with the 7.3.3 image in order to upgrade to 7.3.3 Build 3002. Depending on your current version, you may need to re-image to 7.3.3 Build 2663, then perform an in-place update to build 3002.

Recorder restore images are available here.

Enable Windows Explorer Shell

To perform the following administrative tasks, you must temporarily enable the Windows GUI through the internal settings of the Recorder software.

If you are unsure how to do this, please open a Case with Mediasite Support.

Configure WinHTTP to use TLS 1.0, 1.1, and 1.2

The result of this process will Enable TLS 1.0, TLS 1.1, and TLS 1.2 as default security provider for WinHTTP calls. For additional details on WinHTTP, see this Microsoft support article.

1. Start the registry editor by clicking on Start and Run. Type in “regedit” into the Run field.

You will be editing the registry.  This could have detrimental effects on your computer if done incorrectly. It is strongly advised to make a backup of your critical files before proceeding.

2. Browse to the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp.

3. Right click on the WinHttp key and select New and then DWORD (32-bit) Value from the drop-down list.

4. Rename the DWORD to DefaultSecureProtocols.

5. Right-click the name DefaultSecureProtocols and select Modify from the drop-down menu.

6. Ensure that the Value data field is set to 00000A80 and the Base is Hexadecimal. Click on OK.

Value 00000A80 will enable TLS 1.0, TLS 1.1 and TLS 1.2. To enable TLS 1.2 only, set the value to 00000800.

7. Browse to the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp.

8. Right click on the WinHttp key and select New and then DWORD (32-bit) Value from the drop-down list.

9. Rename the DWORD to DefaultSecureProtocols.

10. Right-click the name DefaultSecureProtocols and select Modify from the drop-down menu.

11. Ensure that the Value data field is set to 00000A80 and the Base is Hexadecimal. Click on OK.

Value 00000A80 will enable TLS 1.0, TLS 1.1 and TLS 1.2. To enable TLS 1.2 only, set the value to 00000800.

Disable Windows Explorer Shell

It’s strongly recommended that you disable the Windows Explorer shell.

Restart the Recorder

Click: Start > Restart to restart the Mediasite Recorder.

Repeat for all recorders

These steps must be taken for all Recorders running Mediasite Recorder software 7.3.3.
