If The IP address of ETH03 cannot be seen in Comfort Server Manager, it could be due to the presence of more than 1 Network adaptor in the PC, for example wifi and Ethernet Network adaptor.
Comfort server manager will transmit a broadcast UDP packet to the 1st network adaptor containing the message, "Discovery: Who is out there?" on the local network to port 30303. If any ETH03s are connected to the network, they will respond with a UDP packet containing their host name and MAC address and IP address If there are more than 1 network adaptors in the PC, the UDP message may be sent to the wrong network adaptor. Note that Managed switches and Routers may also block port 30303 thus preventing discovery
To fix this you can prioritise the network adaptor used by Comfort Server manager to send the UDP discovery.
go to Control Panel. Select Network and Internet > Network and Sharing centre
you will see your network adaptor in the screen.
click on Change Adaptor settings on the left
right click on your networkk adaptor, eg Wifi in my case and select Properties
In properties look for Internet Protocol 4 (TCP/IPv4)
select Advanced
There is a box called Automatic Metric which is checked ie selected by tick
Uncheck it and enter 1 in Interface Metric
Press OK
This will ensure that the network adaptor is selected first when Comffort Server Manager looks for the IP address of ETh03
