Connection server Replication issues
Troubleshooting tools for VMware Horizon (view)
Troubleshoot replication problems between VMware Horizon View Connection servers
- check replication status
   repadmin.exe /showrepl localhost:389 DC=vdi,DC=vmware,DC=int
- force replication
   repadmin.exe /replicate localhost:389 remotehost:389 dc=vdi,dc=vmare,dc=int
- remove failed connection server
   vmadmin.exe -S -r -s serverName
Note: Replication is a multi-master operation.
          Often removing server and rebuilding it is the best course of action.
