> For Domain Controllers, Windows DNS servers and Microsoft Exchange servers, set the "Allow Datagram Processing On WinServer" to **"Datagram processing on Windows Server is disabled"**. These roles often generate high volumes of UDP traffic, which can affect network performance and reliability when datagram processing is enabled. Disabling this setting helps maintain network stability and optimize resource usage in demanding environments.
