Horizon configuration settings are stored in the local AD LDS database on each Connection Server. If the Horizon Connection Server software becomes corrupt, you can simply uninstall and reinstall it without having to perform any additional configuration.
If a Horizon Connection Server cannot be accessed due to a hardware or software failure, and you need to replace it, you must remove it from the AD LDS replication set first. The following steps should be executed from an existing Horizon Connection Server. In this example, we will remove the server named horcon2 from the AD LDS replication set using the vdmadmin.exe utility:
- Navigate to the Program FilesVMwareVMware ViewServer oolsin directory.
- Execute the following command:
vdmadmin.exe -S -r -s horcon2
The failed Horizon Connection server horcon2 has now been removed from the AD LDS replica set and can now be replaced.
To learn about all the options available for the vdmadmin.exe command, run vdmadmin.exe /?.
To restore or replace the server, simply reinstall the Horizon Connection Server on a replacement server and follow the procedure outlined in the Deploying a Horizon Replica Connection Server section of this chapter. The software will be installed and the server will be joined to the existing Horizon Pod.
