The App Layering Agent (PVS Agent) on the PVS server is registered with the App Layering ELM virtual appliance, and the PVS Server enumerates on the App Layering PVS connector screen. However, clicking "check credentials" an error is displayed stating that the ELM cannot use the credentials on the PVS server since it does not have the rights to execute remote PowerShell commands.

You may also see "Cannot communicate with PVS on server 'ServerName'. Please ensure that the PVS Powershell Snapin has been registered".
