Problem:
When trying to manage an RDS farm You receive the error ‘The following servers in this deployment are not part of the server pool: servername.domain.com. The servers must be added to the server pool.
Solution:
To resolve I added the server back into the server pool with the below steps.
1. Open Server Manager
On the Windows desktop, start Server Manager by clicking the Server Manager icon on the Windows taskbar.
2. Then on the Manage menu, click Add Servers.
3. Then do either of the following.
On the Active Directory tab, select servers that are in the current domain. Press Ctrl while selecting to select multiple servers. Click the right-arrow button to move selected servers to the Selected list.
On the DNS tab, enter the host name or IP address, and then press Enter or click Search. Select the servers that you want to add.
4. When you are finished adding servers, click OK.
Close server manager and when you open again you will then see that you can fully manage your RDS environment
