  • DHCP Using external IP Address

    Afternoon guys,

    I have just finished setting up my test network for 70-284 with one little problem.

    I have two VM's (Windows 2003 SP1 fully patched) one VM has 2 nics

    Eth0 - connected to my 10.x.x.x net work
    Eth1 - Connected to my virtual 192.168.x.x network where the other server is located.

    This is so both machines have internet access and I have routing and remote access configured so I can connect to both machines via remote desktops from my main pc on the 10.x.x.x network.

    The problem I am having is that when I went to set-up DHCP server01 thinks it's IP address is 10.1.1.x when it should be 192.168.0.1 - It's using eth0 as it's IP address instead of Eth1.

    Anyone know how to change this?

    Eth0 does not update DNS and is other there as a connection to my physical network for me to access the VM and internet access

    Thanks

    When I ping server 01 from server 01 I get the 10.1.1.x address
    when I ping server 01 from server 02 I get the 192.168.0.x address

    Within the eth0 properties I have disabled update dns and checked DNS and there is no reference to the 10.1.1.x ip address

    I have also ran ipconfig /flushdns

      Fixed!!

      Advanced settings in network Connections and then move the internal interface so it's above the external interface in the connections box. A simple ipconfig /registerdns and then ipconfig /flushdns and the server replys as 192.168.0.x and all is well.

      I knew it was something simple but just couldn't remember what
