    I have 4 VLANs in my office. My Win2003 Standard server is
    on VLAN1. When my XP clients are in VLAN1, they can joined
    the domain. However, when i move the PCs to other VLANs,
    and making changes to the IP settings correspondingly, they
    cannot find the domain server anymore. I will get an "rpc
    server is unavaliable" error after 5mins. Routing between
    the vlans is done by a Cisco 4506 core switch which support
    layer 3. Pls advise


    Also, our corporate DNS server with like "comp.com.au" Can
    I configure all the workstation to keep the DNS suffix sas
    the above and still have acces to my server? Do I need to
    use "comp.local"?

    Thanks in advance to all

  2. The Active Directory DNS on the DC must be the DNS that all machines use.
    Other DNS Servers not related the Active Directory are used by including
    them in the Forwarder's List in the AD DNS Server.

    As Phillip said, the clients use DNS and its SRV records to log on. To do
    this properly, their DNS settings must point to your local DNS server which
    contains these records. If you expand your DNS you will see these records
    (starting with an underscore) which allow clients to find AD services like
    netlogon. If they are not there (or are not found because the DNS setting is
    wrong), you are trying to logon using the Netbios name of the server, and
    that will fail in a segmented network without WINS.

    So make sure that the entries are in DNS, and ensure that your clients
    point to the correct DNS server to find them.

    Phillip,

    Do you mean my PCs must be in the same domain as the DC.
    Could you provide me info.

  5. Your subject says that the XP machines can not join the Domain from another
    subnet. I said *all* your machines must use the AD DNS server (not some
    other one) or they won't be able to find the DC while in other subnets
    because they cannot "broadcast" to find it. Broadcasts don't cross routers.
    Wether it is a VLAN or hardwired Subnet is not relevant, the principle is
    the same.
