Hi all,

One of our servers is on a slowish adsl connection, and we just got a bill
for the account that says we did 5.5gig on that account in the last month..

There is nothing running on it which should be consuming bandwidth... I can
maybe account for 1 gig, but not 5.5

The only thing the server is doing is a dns server, and a gateway to a
couple of low usage web servers, (one win2000 one linux)

The 1 gig I can account for is all the patchs and updates for the 3
machines.. (mostly win2000 patches,,, lets be honest here... :-)

a look at the logs,, shows an awful lot of dns requests and responses.... I
haven't seen this much dns traffic on this machine before... (I have changed
the domain of our server,,, to ns.epay.net.au)

does anyone know what is going on here?? this is about 5 seconds (we logged
2 minutes worth and its huge....)

something I don't understand is going on here and its costing us big
bucks...


Any ideas anyone???
