This is something I need though since on rare occasions (cough) one of the Windows boxes running DNS gets a little ... ehm ... sluggish. A situation which impacts performance all around for scores of applications. </p> <p>Incidentally I am running all this on a Quad-CPU smp kernel 2.6.9 Red Hat EL 4 box. Scanning through recent messages that seems to be important too.</p> <p>Any suggestions are welcome.</p> <p> </p> <p>Cheers,</p> <p>Hans Engelen</p></div>
