If you are connecting to a computer or device with testconnection.exe or devicetester.exe to troubleshoot a scanning issue, you must run these tools from your Lansweeper server, i.e. from the server hosting the Lansweeper Server service that scans your network. The warning you are seeing indicates that the tool is not being run from the Lansweeper server, which makes the test output unreliable for troubleshooting purposes.
