RDS 2012 R2 - Server Manager Won't Show RDS Deployment

Scenario

Ok so you know that you installed your RDS roles and your server manager used to show you your RDS deployment.  But today you logged in and you get the above message: "A Remote Desktop Services deployment does not exist in the server pool.  To create a deployment, run the Add Roles and Features Wizard and select the Remote Desktop Services installation option".

When this happened to me, I verified that the RDS roles were in installed - they were.  My remote apps still worked, the roles were still there, etc.  But server manager would not recognize the deployment.

Highly Available 2008 R2 RDS Infrastructure

SCENARIO: Deploy highly available 2008 R2 Connection Broker. There are different ways to do this, but in our scenario, we will cluster the connection broker server, create a shared cluster service, and use NLB to balance the initial connection load on the session hosts.

PREREQUISITES:

SESSION HOSTS
2 Server 2008 R2 Servers with Session Host Roll installed
Session Host servers should have two NIC's (One for RDP and the other for NLB)

CONNECTION BROKERS
2 Server 2008 R2 servers with Connection Broker Roll installed.

Ensure that all servers are members of the same domain.
Ensure that all servers are able to communicate with each other (work out subnet / VLAN issues if any exist)

STEPS OVERVIEW
1. Install Failover Cluster feature on Connection Brokers
2. Create drive / folder for quorum drive (this is for failover clustering and in this example we will use a folder)
3. Create share cluster service.
4. Install NLB on Session Hosts.
5. Configure NLB on Session Hosts.
6. Create Session Host Farm.
7. Create appropriate DNS entries.
