    We have just set up a new W2003 Server using high-end Dell hardware, a
    domain with a single PDC. The workstations are Dells as well, but Dimension
    4700s, running XP Pro.

    The process of logging into the server is amazingly slow, requiring
    sometimes 60-120 secs. There are no special profiles or drive mappings,
    essentially the most basic of configurations.

    Can anyone suggest what might be causing this? BTW, workstations are Fast
    Ethernet and the server/switch link is a Gigabit Ethernet connection.

  2. sounds like DNS issue. quoted from
    Why is XP running slower while logon 1

    When I login into a Windows 2000 active directory from a new xp pro machine
    the login in is extremely slow. After logged on, everything works fine. But
    other windows versions don't have this problem.
    A: This is almost like name resolution issue. Comparing with previous
    versions, XP is heavily dependent on DNS to find DC. If the DNS is
    configured incorrectly, XP will take longer time waiting for it to timeout
    before it tries using NetBIOS. Make sure
    1) The DNS setup correct and have the server information.
    2) XP clients can find the DNS server.
    3) XP machine's DNS server is pointed to your internal DNS server rather
    than your ISP's DNS server.
    4) Make sure no errors on logon scripts or GPO's that could be causing
    the delay.
    5) Check any errors on event viewer.
    6) Disable NetBIOS on the interfaces that client will not use.

  3. Most likely the DNS for the clients is not correct. The Primary DNS IP on
    the clients (and the DC) should be your DC. If the primary DNS is anything
    but a DNS server for your domain, login will be slow and other issues will

  4. Hi David,

    One of first things to check is DNS configuration on the clients. You
    clients DNS settings (Preferred DNS IP address under TCP/IP Settings) should
    point to your active directory DNS (probably your Active Directory server).
    Clients should not use any other DNS servers (e.g. your ISP's DNS).

    Another thing to check is DNS settings of your domain controller. Just like
    clients domain controller must also point to active directory DNS -- in this
    case probably back to itself. If you domain controller is also DNS server
    then you can enter for preferred DNS server on your domain

    Note: it is not very smart to only have one domain controller in production
    environment. Restoring domain from tape can be pretty hard task - specially
    with users calling every few minutes and asking when the domain will work

    Thanks for these replies. Sounds like there is a consensus.

    In fact, we have not configured DNS at all -- assuming we needed it only for
    Internet access, we would merely use the ISP's DNS as we always have with

    Obviously, out of my league with this new server version.

    That won't work with Active Directory. NT used Netbios names to find a
    logon server. Active Directory clients use DNS for this. So the clients need
    to point to your local DNS to find a logon server (and a lot of other AD
    services as well).

    To get the clients access to "foreign" DNS names, set your DNS server to
    forward requests to a public DNS service (such as your ISP).

    Thanks for your help, everyone.

    I guess I'm going to have to come out of the dark ages, after all...
