    Hello, around last month we started to lose lan connections to our NAS.
    We wanted to replace it anyways since it was old and did not have
    encryption.

    So we moved the data to the boses machine and we have still experienced
    lan drop out so here is a list of what has been tried and replaced.


    1. router replaced
    2. switch replaced 2x
    3. switched out machines new machines still drop
    4. added new nas nas still drops
    5. changed from wired to wireless still drops
    6. changed network cards. still drops


    Please help.

  3. Hi
    Changing from Wire to wireless is not necessarily a general indication.
    Start by connecting two computer to the switch with new commercially made
    wires.

  4. Hi

    Please drop the microsoft.public.msmq.networking newsgroup from the thread
    as the MSMQ guys won't be able to help as much as the other networking
    newsgroups already involved.

    Cheers

    seems my messages weren't getting through. I connected the computers
    static ips to the switch with new cables and they still drop.

    IS there a program i can install on the computer to monitor the network
    and report what happens like wireshark? would wireshark be good to trac
    what computer is causing the network to drop?

    sorry that was in my earlier messages that were never posted for some
    reason.

    drop means you will lose connectivity to the devices eg you can no
    longer ping them, depending they will come back up after 2 minutes or
    longer. sometimes they don't come back up without a restart or power cycle.

    no voip system here. However I am changing every network card in the
    systems and seeing if that works. Right now all machines have a static
    ip and are connected to a switch with no router and seeing if any thing
    drops. every machine is also being tested one at a time connected to the
    switch and NAS with a large data file being transferred to see if it
    causes any problems.

    Ok it turned out 3 network cards were bad, one router had massive packet
    loss, and one network cable needed to be replaced. After all that was
    fixed systems ran great until...

    the receptionists computer decided to die and it sent a surge through
    the network killing off everything that was fixed.

    Replaced everything again switch survived and they are now up.
