slow connection to network shares in explorer

    We just migrated a bunch of folders from a novell server to a win 2k3 r2
    server and have a couple of drives mapped to letters (G: and H:) when users
    logon.

    When you open file explorer to get a file off the network share, it is very
    slow to respond (5-10 seconds). After the initial connection then it seems
    to be OK for that share, until you reboot. Is there any way to pre-connect
    to these shares when you logon so there is no delay when you browse to the
    mapped drive?

    thanks,
    Bill

  2. I presume you've got a login script. If you go to start | run, and type in
    G:\ <enter> what happens?

    after about 10-12 seconds, the shared drive shows up in a explorer window

  4. If you open it to C:\, what happens?

    Are you using AD?

  9. I hope this is actually something like ourdomain.local - not a single label
    domain. Correct/
    OT, but this should be "hybrid" - in your DHCP server, set the WINS node
    type to 0x8. Won't be related to this problem, however.
    What's that 2nd DNS server IP pointing to?

    In general that looks fine. So, I'm wondering about hardware. Are you using
    a hub or a switch? You want to use a good switch. Try swapping out cabling,
    switch ports. If you get no joy there, try locking down your server &
    workstation NICs at 100/full (rather than using Autosense).

    can you elaborate on this?

    another domain controller



    I don't think its a hardware issue, the connections to the novell server are
    extrememly fast. the connections to the windows servers are only slow on
    first connection (about 10+ seconds) then after the files are displayed the
    connection is fine.

  11. What's the *unedited* content of the DNS suffix? It should be something
    *dot* something, not merely *something* which would mean it's a single-label
    domain and will have problems.
    http://www.mombu.com/microsoft/windows-2000-dns/t-single-label-dns-names-why-153683.html
    has some useful info (see Ace Fekay's post). Also
    http://wiki.answers.com/Q/What_is_a_Single_Label_domain_name_and_what_sort_of_issues_can_it_cause
    and
    http://www.google.com/search?q=AD+D...avclient-ff&ie=UTF-8&rlz=1B3GGGL_enUS297US297

    Note that there is really no need to edit or munge anything when posting an
    ipconfig /all in here. Nobody could do anything with the information. It's
    all internal.
    ....running AD-integrated DNS, I trust?

    here's the fix:

    uninstall Client for Microsoft Networks
    uninstall File and Printer Sharing for Microsoft Networks
    uninstall QoS driver
    reboot
    reinstall client and file sharing.

    problem solved - works like a charm.
