However, according to tcpview.exe (from sysinternals) there are an
uncountable number of DNS UDP connections.

I'm not sure about "uncountable", the number is probably around 2500 or
so. This is normal.

tcpview crashes.

Now, I have used QoS, to set the network traffic to just 1Kbit/s up/down
what can I do more to protect the server against an overflow of connections?

Overflow of connections? Do you know how DNS works? (Free hint: Those
2500 UDP ports, are connectionless)

Thanks but you can leave out your sarcasm...
If you feel superior because of knowlegde; free hint: you are not.
