I'm hitting a wall here so need some help.
I am currently involved in a project that will require use of a third party software installed on one of our internal servers.
The software in question will be responsible for managing range of mobile devices in our warehouse and production areas. The problem is that the software vendor requires the software to use an SSL connections signed by authorised CA, self-signed certificates are not an option.
Everything will be run on internal network inside ActiveDirectory domain, with no access to outside world whatsoever.
I tried using the ZeroSSL service (which utilizes LetsEncrypt) but it's obviously no go, even using the DNS verification, since the ZeroSSL & LetsEncrypt cannot query my internal DNS for the TXT records.
So how do I get a CA signed SSL certificate on windows servers without any access to internet?
