    Can anyone explain why the first packet is to the default gateway and not the DNS server?

    I have a client machine set up
    IP 192.168.1.2
    default gateway 192.168.1.1
    Primary DNS server 192.168.1.53

    What confuses me, is when I clear the NetBIOS and DNS cache, and then try to ping another computer on my network by name,
    eg 'ping computer2'

    The first packet sent is a DNS packet, requesting the IP of computer2.mydomain.com
    But it is sent to the default gateway

    The next packet is the same but sent to the IP I have said is the DNS server, this the packet I expected to see first.

    Can anyone explain why the first packet is to the default gateway and not the DNS server?

    Hope that is the only required information. If you think you can answer, with more information, just ask.
