Decommission a Horizon Connection Server

Most of the time we install softwares but seldom uninstall stuff. When you are doing some lab testing or POC (proof of concept), we need to do some proper cleanup.

The key for uninstalling a Horizon Connection Server properly is removing AD LDS Instance and running the vdmadmin command as the last step.

1. Control Panel > Horizon Connection Server > Uninstall
   
   
   
   
   
2. Uninstall HTML Access
   
   
   
   
   
3. Uninstall AD LDS
   
   
   
   
   
4. Hold up. The entry still exist in the Horizon Administrator Console.
   
   
   
   
   
5. Go to the first Horizon Connection Server's Windows operating system. Run this command to clean up the entry.
   
   vdmadmin.exe -S -r -s <hostname>
   
   The hostname is the Horizon Connection Server that you had uninstalled.
   
   
   
   
   
6. Go back to your admin console and verify it had been removed.
