  3. In
    Are you using AD?
    Are you using WINS?

  4. Have you done any connectivity testing when the problem occurs
    e.g., ping by tcp/ip address or by name? Checked the system log
    in the event viewer for any related errors? You say they lose their
    mapped drives but you didn't mention errors of any kind e.g., does
    the drive disappear, they get an error? Without rebooting have you
    tried to re-map the share? If so what error do you get? It would be
    hard to give you any advise without more details.

    The only way to reconnect is to reboot. There are no errors in the log files.
    I did just notice that the server is no longer listed in Network Places on
    any of the computers.

  7. So can we assume ping by tcp/ip address failed or does the server crash /
    lockup? The reason I ask is to try and narrow things down in an attempt
    to find your issue. The standard troubleshooting calls for a simple ping by
    tcp/ip address, if this works then chances are you can rule out NIC,
    cable or rounting and move on to name resolution. If it doesn't work then
    start with the NIC. Ipconfig /all at a command prompt to verify the NIC
    is getting an address next move to cable or routing. You have to find the
    cause or root of your issue in order to resolve your issue.

    I can ping the Server by its IP but not name. The workstations get an error
    saying that it is now working offline from the ServerName click here to try
    and connect. I click and it gives me a timeout error. I restart the
    Workstation (they are all 2KPro) and everything works great. Could it be a
    DNS issue? I have not changed anything there since initial install. But it is
    very strange that the sever is no longer in Network places when you click
    entire. All other workstations are there????

  9. I have experienced similar problems, but a long time ago. I had a client
    with a faulty switch that kept flapping certain ports. When the conenction
    to the DC was broken, and the clients had Offline Files configured (as well
    as folder redirection), the same scenario you described would happen.

    I don't know if it was a result of Offline Files, Folder Redirection, or
    having both on the same machine...

    Either way, check the switch and make sure it isn't faulty or overloaded.

    Our 24 port is full so I will switch some computers to another switch that is
    still in the box and see what happens. Thanks

  11. Our 24 port is full so I will switch some computers to another switch that
    If you have a resonably good quality switch, you should be able to log in
    and check the status and performance levels etc...

    What kind of switch is it?

    It is an HP ProCurve 2425.

  13. It is an HP ProCurve 2425.

    It has a fairly robust CLI. You shoudl be able to log in and gather port
    statistics.

    Idealy you should move the DC to the new switch for testing purposes. If all
    your clients have the same problem, it's unlikely to be their ports that are
    the issue. However, this will also increase the bandwidth requirements of
    your uplink ports (unless they a gigabit ports) so be careful.
