In some instances the console will open but the exeption will be thrown when trying to select any node. Operations Manager consoles hosted on remote workstations will also exhibit similar behavior. Attempts to open the Operations Manager command shell will time out and no cmdlet using the Operations Manager provider will return data.
This can occur if the communication channel to the OperationsManager database from the System Center Data Access Service (SDK service) is failing due to a protocol error.
