We set up a RD Gateway to use RemoteApp on our server. We installed an SSL certificate from Comodo into IIS, so RDWebAccess is reported as being secure.
However, for the actual RD connection, we are using a self-signed cert, so it works but is reported as untrusted.
We are unclear as to how to obtain a real cert for the gateway and broker from a third party.
I haven't been able to find anyone selling certs that would be applicable to the gateway. I also tried setting up a Microsoft CA server, but am getting lost in the process to create a root CA, and then generating a cert for gateway using that...
From what I can tell, we created a root ca, then generated a cert from that for the gateway, and installed. But, upon logging in remotely to the gateway, it appears our self-generated root ca is not trusted (since its not affiliated with a third party ca???
I am able to easily load this cert into IIS and bind it to server1.sub.domain.net port 443
However, when I try to configure certificates for RD gateway, broker and web access by selecting existing certificate, it is looking for a certificate ending in .PFX
