We have some Windows servers that are behind a firewall, and have no access to the Internet. Some of them are Web Servers (for intranet), and some are application servers, database, file, etc.
Some of the applications require login, and due to the lack of SSL certificates, the browser will display a warning to the user whenever it sees in input field on the page.
We can't configure the Web Server to use HTTPS since it lacks the SSL certificate.
My Question is: Is there a way to configure the server to use HTTPS even though it has no access to the Internet?
If yes, then how can the certificate be installed on it? I understand that I must purchase a certificate from somewhere, but how do I install it on all of the servers?
Where can I read more about these things that apply to our setup?
