    other files     // may change counter values whereever needed, through:
                    //   public functions & public counter pointers (see dnsperf.h)


//====================================
NT setup:
  copy     dnsperf.ini  dnsperf.h  dnsperf.dll
    to  %windir%\system32\
//====================================


To add new counters for DNS:

    See datadns.h for help.

    Tip -- to view the places to be changed by following the example of
           the first counter, TotalQueryReceived :

        At  dns\server\server :
          type 'qgrep -y TotalQueryReceived *'
        At  dns\server\server :
          type 'qgrep -y TotalQueryReceived *'
