    Hi,

    We have setup a Site to Site VPN with a client but I'm stumped when it comes
    to how to configure the DNS for this.

    To access one of the hosts on our clients network we have to use their
    internal network ip address.
    When I set this up in the hosts file of a pc it works fine.

    The issue I have is I don't want to do this on every PC but the hostname
    resolves to a public ip address if I let the internet dns resolve it which we
    don't have access to.

    Can I configure my Windows Server DNS to resolve these hostnames to the
    internal ip address of our client?

    Thanks.

  2. You can use DNS or WINS

    With DNS create a Host Record (an "A" Record) for the name of the machine
    and configure the correct IP#.

    With WINS you just create a new Static Entry.
    The Clients involved have to actually be using the WINS Server for it to
    matter.

    A third possiblity is a Conditional Forwarder in DNS. But it depends on:

    1. The DNS Server of the Client is reachable and will respond to you

    2. You have to use the full FQDN (based on the other company's domain name)
    when accessing the Hosts or it will not trigger the Conditional Forwarder

  3. Just to add, I usually configure this type of scenario with Conditional
    Forwarders,which will work with one host or all hosts, but as you've
    indicated, the FQDN has to be used, unless the source machine has the search
    suffix of the partner machine it will resolve using a single name as long as
    there isn't a duplicate name on the source domain.

  4. Have you tried just creating a host (A record) on your dns server? Not sure
    why you would want to create a host file when a simple A record is all that
    is required. I'm guessing there is something not defined within this
    scenario.
