RD Broker Windows Internal Database running even in HA mode?

Hi,

While looking at the performance monitor on my active RD broker, I noticed that the Windows Internal Database process was running. I was under the impression that when you configure HA on the RD Brokers, the WID was replaced by the SQL Database, as it is configured in the High Availability Settings.

Can anyone explain this? Is it safe to remove the WID on the RD Brokers?

Thanks
