DNS Setup Problem/Question

Discussion in 'Windows Networking' started by Ther Richardson, Apr 27, 2007.

  1. I have a Win 2003 Native domain, for example we will call it
    building.org. I am setting up a second domain in the forest that will

    In building.org I have 2 Win 2003 servers running DNS all set up (by me,
    several years ago, and now I don't remember much about it) should the new
    domain ortherbuilding.org have its own DNS server? At some point very soon
    Cisco will be putting in place VLANs to keep residents from the domain
    ortherbuilding.org from seeing computers servers printers etc. on
    building.org. the three servers in question are

    building.org Primary DNS server
    building.org Backup/Secondary DNS server.
    Both point at themselves first and have the other as secondary

    otherbuilding.org During DCPOMO it installed and auto
    configured DNS I have tweaked it just enough so it does not have the
    loopback address in it instead of 192.168.11

    My questions are...
    Do I need DNS on the new server in otherbuilding.org?
    If yes what should I make the pri and sec DNS addresses?

    Sorry, but I cross posted to networking as well.

  2. As long as the DNS servers are on a port that is a member of both the
    building.org VLAN and the otherbuilding.org VLAN (a multi-VLAN port), then
    you don't need a new DNS server. Both buildings can use the same servers.
    However, you will need to make sure that both domains are served from these
    DNS servers. Both buildings would then be able to resolve hosts on both
    networks, but they would only be able to reach hosts on their VLAN.

    If you restrict the DNS servers to the building.org VLAN, then you'll need
    DNS on the otherbuilding.org VLAN. There won't be a secondary DNS server or
    secondary DC if you only have the one server on this VLAN. There would be a
    client primary DNS server setting, but the secondary would be blank.

  3. Any thoughts on why my dns server can see all the other computers on this
    domain and the first domain but not itself? Likewise all other computers
    can see all other computers accept new server. it does not apper in any

  4. When you say the DNS server cannot see itself, what do you mean?

    If i explore network neighborhood i can see all the other computers in the
    two domains in the kist but the dns server in the new domain does not show
    up with them.

    network and I see all the other servers and workstations save one, the new
    dns server in the new domain.
