Firebird 3 - Unable to Complete Network Host Connection
Without an active network connection ( LAN / WIFI) a localhost FB3 server (like most business agents run on their laptops when onsite) will report “firebird unable to complete network request to host localhost”.
This is due to Network protocol in Win10 called Media Sense. To combat this you will need to disable it by default.
To disable Media Sense, perform the following steps
- Click on the Start button.
- Type cmd in the search bar.
- Right click on the cmd.exe and select Run as Administrator.
- Run the following commands one by one:
- netsh interface ipv4 set global dhcpmediasense=disabled
- netsh interface ipv6 set global dhcpmediasense=disabled
- After finishing the commands above, please run the following commands to check the results:
- netsh interface ipv4 show global
- netsh interface ipv6 show global
Check if the entry “DHCP Media Sense” shows disabled or not. If it is disabled, it means the operations were successful.
However, please also note, the Media Sense depends on the NIC; if the NIC didn’t support the Media Sense, the configurations won’t take effect, either. Therefore, please also check the issue with the technical support of your NIC.
