I can't get any output at all when transferring the whole range through the files:
netscan.exe /hide /config:netscan.xml /auto:result.xml /range:192.168.1.1-192.168.1.254 >> output.txt netscan.exe /hide /config:netscan.xml /auto:result2.xml /range:192.168.2.1-192.168.2.254 >> output.txt
If I then scan those ranges again, the output files appear without problems.
