Applying a DNS record only to one Subnet in the forest

    Întrebare

  • Hello all,

         I have a mail server that sits in a DMZ at one branch location. We have mobile users that have their mail programs setup to go to mail.mycompany.com. But when they are inside the branch that houses the email server it wouldn't work. This was because I didn't have a DNS record setup for mail.mycompany.com. So I set up that record which made it work. <o:p></o:p>

         My issue is that we have a VPN tunnel between corp and the branch offices. So when the mobile users move from the branch office that has the mail server to another office the DNS record doesn’t work. Because the tunnel does not allow users to see the DMZ where the email server is from the other offices. But it is all under the same domain just different subnets.<o:p></o:p>

         I do have all the stores on their own subnets. So is there a way to have the record for Mail.mycompany.com point to the DMZ IP at the branch the mail server is located at. But have mail.mycompany.com at all other branches aim toward the WAN IP address of the mail server?

    <o:p>Thanks in advance!</o:p>

    That depends on how you have your DNS configured and how the clients
    get the proper DNS servers when they connect. You'll need a DNS server
    in that branch office and another in the other office and the correct
    DHCP scopes. This really isn't an Exchange question, though.
