Pontus,

Hold on a second. Nessus has been known to falsely identify windows DDoS tools. Check everything out on those boxes before you jump to conclusions.

I strongly suspect that you've got false positives on your Nessus report, as I have many times in the past. Remember, Nessus isn't the end all and be all, it's just one tool.
