Server 2012 RemoteApp Troubles

I have one that has me completely stumped here, looking for suggestions.

I have a new RDP deployment on 2012 with the following:
2 Connection Brokers with HA enabled to SQL
2 Session Hosts
2 Gateways

The deployment seems to be healthy. No errors during setup, whatsoever, certificates are all applied. I've built smaller non HA deployments in the past and have never really had any problems before.

The issue is that the RemoteApps are broken. After creating the collection, then publishing WordPad for example, the resulting RDP file that is downloaded when you access rdweb is incomplete.

If I look inside, it's missing the signature section to sign the RDP file, missing the gateway information, and even the full address line. So needless to say the RDP file doesn't work.

Not really sure what to do here as 2012 builds the RDP file based on the information that you specify in the collection. I've tried removing the collection, re-adding it, but it still gives me this RDP file that doesn't have any connection information inside.

Any ideas on where to even start with this?

Turned out to be the certificates, Even though I didn't have any errors when I initially deployed the certificates, something must have gone wrong. I re-deployed the certificates to all the deployment members through the deployment settings and everything worked fine after that.
