VMware Horizon Agent “Protocol Error” — Fixed by Windows Firewall Configuration

  🖥️ VMware Horizon Agent “Protocol Error” — Fixed by Windows Firewall Configuration Overview Recently, I encountered an issue where several Horizon Agent–based virtual desktops in our environment showed the status “Starting other services” or “Protocol Error” in the Horizon Administrator console.
