This topic applies to KCT NG 2026.2 and later. If you are on KCT 3.12.7 or earlier, see legacy topic.
SolarWinds does not recommend usage of Trivial File Transfer Protocol (TFTP) in KCT NG due to potential security vulnerabilities. If TFTP must be used, it is highly recommended to take precautions and limit its exposure
The TFTP service can run on only one application at a time. If you have TFTP enabled in KCT (version 3.12.7 or earlier), you will need to stop the service before enabling it in KCT NG.
