If you're setting up a machine or adding FLOW and/or Ark roles to a server besides your EFS master server, the expected icons may not immediately appear on the server's landing page.
This may also be necessary after changing the IP addresses of any services displayed on the landing page. (i.e. FLOW Control or FLOW Automation)
To refresh the master server's landing page so the correct links are displayed, run through Role Assistant on the EFS master server and reboot, then check the server's landing page again.
