When I run the Comfort Server Manager 2.0.6 (CSM) on my 64 bit Windows7 main computer, it will not / can not find my UCM/ETH03. However, if I run the program on my 32 bit Windows7 laptop - same network; same network switch; same subnet etc - it finds it instantly. The ETH03 has a static address and on the 64 bit machine, I can happily read from, or write to the Comfort box using Comfigurator - even though the CSM won't find it. I have tried turning the firewall off on the computer, but to no avail. Is there a problem with 64 bit Windows running CSM?

Comfort server manager can be used with 64 and 32 bit windows
The problem may be due to blocking of UDP port 30303 used to discover the ETH03

I don't think that port 30303 is being blocked, but what Wireshark is showing me is that the discovery packets are being sent from an address that is NOT my computer! In fact, not even my subnet!
46 3.225923000 192.168.56.1 255.255.255.255 UDP 70 Source port: 30303 Destination port: 30303
and my computer's address is 192.168.100.160
I don't have any network interfaces within that range at all - so where is the CSM getting that address to send the packets? No surprise it isn't seeing ETH03!

i think wireshark only shows traffic to/from your own computer so your PC network may be set up in a weird way
Try running wireshark from another PC (but dont run cs manager) and see if it can see the same IP address

Thanks for all your help. I think I have found the problem - although not the cause! I have a virtual machine on my PC and the VirtualBox network adapter address is - yes, 192.168.56.1. So it appears that the CSM had "attached" itself to that address - even though the virtual machine is not / was not running. I have downloaded a clean copy of CSM; disabled all network adapters other than the one Ethernet NIC and run the 'clean' program - and it worked straight away. I've overwritten the original CSM .exe file in the Cytech directory, and everything is OK. But...how did the CSM get the virtual adapter address in the first place? Weird! One for the files......

I'm glad you found the problem. The 192.168.56.1 is exactly the same as my VM interface. Just check that the OS doesn't prefer that one over the actual physical interface or perhaps a strange static route somewhere. Check the metrics when you do a 'route print', it should tell you which one is preferred(lowest = better).

For those running Windows 10 on Mac using Parallels, and cannot see ETH03 in Comfort Server Manager;Try changing the network mode from Shared to Bridged. This allows the IP addresss to be in the same network as the home network so CS Manager can talk to ETH03.
