Hi Everyone,

For the past few days I have found a problem in my pings to any server. They seemed to be randomly spiking and suddenly it would stop and be normal for a few more minutes before spiking again.

I have just isolated the issue and it seems to be while I am using my Microsoft Server 2008 R2 DNS Server with forwarders, this spiking happens. See what I mean below.

I have no idea why or how this occurs? Surely pinging does not resolve the IP each time, so therefore the DNS Server should not even be a factor?

Thanks in advance
