Root Server Configurator is started during device startup and then Root Server Configurator starts all the other servers used for device communication. </p> <p>Examples of these servers are the <xref href="GUID-61E0CD76-A2E3-5066-84A8-146EECA8ADCD.dita">Sockets Server</xref>, the <xref href="GUID-D49696D1-4B84-56B5-909D-A15F599F4B6D.dita">Telephony Server</xref> and the <xref href="GUID-9B83CDD4-FC94-51A0-AC67-CD04BCAFEF08.dita">Serial Communications Server</xref>. </p> <p>The Root Server Configurator is a separate process to the Root Server. </p> <p>To start the Root Server Configurator, a process must start either the <filepath>c32start.exe</filepath> program, or must call the <xref href="GUID-CFCBC5A6-FB1F-3DD7-B275-9B9C7389A8A7.dita"><apiname>StartC32()</apiname></xref> function.
