  • Pinging Problems

    I have recently rebuilt the machine that receives fax because it was unbearably slow, but now i have a problem

    Step 1 - Machine A can't ping Fax machine

    Step 2 - Fax machine can ping Machine A

    Step 3 - Now Machine A CAN ping Fax machine

    Step 4 - After 30/45 Minutes of inactivity on the Fax machine, it can't be pinged again

    i thought this was a case of the Network Card falling asleep due to inactivity, but in Step 3 where Machine A can ping it, Machine B still can't unless it is pinged first by the Fax machine.

    i am using XP SP2 and i am using the same Network Card (which was removed from the old Fax machine) which is a "D-Link DFE-530TX PCI Fast Ethernet" card

    the problem with it is that a certain employee cannot VNC connect to it when they need to read the new faxes, because it seems to be in this "sleep" state

    any help or advice?

    Sounds like maybe the Windows (or 3rd party) firewall is on. Check that. Also check your routes (from a cmd prompt "route print") and make sure your gateway and DNS servers are setup correctly.

      I have checked the local firewall and that the DNS is set up correctly, they are both fine, any other suggestions?

        have you tried (as a test) to disable the firewalls, then ping again?

          We have multiple external firewalls so our local XP firewalls are turned off (plus McAfee can't update when they are on)

            Do you ping only the name of de computer or also by its Ipaddress"?
            Have all the computers static Ipaddresses?
            Does one or some, of these computers have more than one NIC?
            Checked the DNS for stale records, and stale ptr records?
            Do you have a wins Server?

            Ping like this from machine A:
            cmd /k arp -d&&ping 192.168.xx.xx&&arp -a
            where the ipaddress is the addres of the fax computer.

              I've just made a breakthrough, turns out it's a faulty switch, going to have to shell out for a new one now

              thanks a bunch though guys!

                Ip-to-Mac address mapping on the switch?
                then try to clear the arp cache on the switch port, before buying a new switch.

                good luck!
