Resolution
Microsoft offers the ability to automatically update all trusted certificate authorities. This functionality has a group policy object that is tied to it that may be disabled in an environment.
This policy object can be found at:
- Computer Configuration > Administrative Templates > System > Internet Communication Management and click Internet Communication Settings > Turn off Automatic Root Certificates Update
Setting this policy to Enabled prevents Windows Update from pulling Microsoft-validated root certificate authorities. Setting this policy to Disabled allows for Microsoft-validated root certificate authorities to automatically be updated through Windows Update.
This policy object within Group Policy is present by default in Windows 10 version 1511 (November 2015 update) or later. For Operating Systems before this release, a Windows Update is required for this process to function properly. These OS-specific updates can be found at Microsoft's KB article 2813430, here:
https://support.microsoft.com/en-us/help/2813430
If disabling this policy is not possible within your environment, manually adding the following Certificates allow for the signature validation to pass. As of Dell Encryption 10.0 or Dell Endpoint Security Suite Enterprise 2.0, the current Root Certificates that are required are:
- Verisign Root Authority
