If you have the task of regularly updating root certificates in an Internet-isolated Active Directory domain, there is a slightly more complicated scheme for updating local certificate stores on domain-joined computers using Group Policies.
You can configure root certificate updates on user computers in the disconnected Windows networks in several ways. The first way assumes that you regularly manually download and copy a file with root certificates to your isolated network.
You can download the file with current Microsoft root certificates as follows:. The second way is to download the actual Microsoft root certificates using the command:. A number of root certificate files CRT file format will appear in the specified shared network folder including files authrootstl.

For systems that are running Windows Vista, Windows 7, Windows Server , or Windows Server R2 and that are using the automatic updater of untrusted certificates that is, if either KB or KB is already installed , see the rest of this section and also Microsoft Knowledge Base article for more information.
Customers do not have to take any action because these systems will be automatically protected. If the system does not have access to Windows Update, either because the system is not connected to the Internet or because Windows Update is blocked by firewall rules, the network retrieval will time-out before the service can continue its startup procedure. In some cases, this network retrieval time-out may exceed the service startup time-out of 30 seconds. If a service cannot report that startup has completed after 30 seconds, the service control manager SCM stops the service.
If you cannot avoid installing this update on disconnected systems, you can disable the network retrieval of the trusted and untrusted CTLs. To do this, you disable automatic root updates by using Group Policy settings. To disable automatic root updates by using policy settings, follow these steps:.
In the details pane, double-click Certificate Path Validation Settings. Click the Network Retrieval tab, select Define these policy settings , and then clear the Automatically update certificates in the Microsoft Root Certificate Program recommended check box.
After you make this change, automatic root updates are disabled on those systems to which the policy is applied. We recommend that the policy be applied only to those systems that do not have Internet access or that are prevented from accessing Windows Update because of firewall rules. If automatic root updates are disabled, Administrators must manually manage root certificates that are trusted by Windows.

Unfortunately we do not have these machines on any domain - they are in their own world at the moment. Okay - update. Unfortunately, installing it manually did no good. However, we have made the decision to open said sites up and allow the CA certificate grabs to go through that way. I cannot locate said list of sites.
