Network issue?

    We have a server at work that is running Windows server 2003.
    The systems that are connected to it are having problems every day at 4:30.
    We are running a program that tracks our jobs in the shop, customers,
    inventory, accounting etc.
    Every day at 4:30, each system loses connectivity to the server which has
    the database on the drive.
    The software company says it is a networking issue and not related to their
    software. I have checked the server thoroughly and cannot find anything that
    runs at that time.
    I have checked with Watchguard to see if it is our Soho6TC firewall, and
    that does not seem to be it.
    Has anyone ever had a problem like this before?

    Each system is running WinXP pro.

    Any ideas?

    many thanks

    Is 4:30 quitting time in your shop?

    Ya, what happens in your building at 4:30? I remember a tale from a
    local trade school where they had their network cables running on the
    floor, then through a wall into the neighbouring class, across their
    floor down to the electrical/patch room.

    One welding instructor had the power cables for his welder running along
    the floor beside the UTP (unshielded twisted pair) network cables.
    Well, whenever this welding instructor turned on his welder the network
    connection to this class would go down.

    You might want to trace the physical path your network cables take in
    your building and see how close they get to any power sources. And,
    what events happen in your building at 4:30?

    We work until 5:30 and sometimes to 8:00
    After a crash, when we restart the systems, everything works good.
    If we leave the Clients on they crash during the night about 8 hours later
    at 12:30 a.m.
    All wires run into the IT room at the same location. None are located near
    power lines.
    I looked in the event viewer and I find a DCOM error about the time this
    happens. One at 8:32
    again at 4:32 and once more at 12:32.

    Thanks

    Ok, something is causing this every day at the same times. So what's
    happening at those times? Users running automated batches or jobs of
    some sort?

    The NT based O/S does have Audit Tracking that will audit and report events
    happening on the machine. It's a good investigative tool. However, taking
    that software off of one of the client machines and letting it do something
    that requires network access to the server should tell you if that software
    you talk about is the problem or is not the problem.I think you have some
    kind of software issue if DCOM is crashing on the machine.

    Good point
    I will turn off the E2 software and see if the network still has issues.
    First I will try the client pc and then the server if the client checks ok.
    I am curious to see if I was to change the time on the server to 4:30 if it
    would happen then.

    Thanks
