  • Strange Networking Issue

    Hi,

    I wondered if anyone had any bright ideas regarding my below issue :

    I have an Exchange 2007 Server, that sometimes people cannot ping and as such Outlook stops working.

    But the server itself if up, you can connect to it, browse the web, ping other network devices, but not the PC in question.

    Then suddenly it will start working again.

    Has anyone seen something like this before?

    I have updated the NIC Drivers on both the Server and the PC's, wondered if the switch could be causing issues?

    There is also another server (file) that never disappears.

    The server is DL380G5
    The workstations are XW4600

    Thanks

    Another device on the same IP address maybe?
    Certainly things like network card drivers, switch firmware, switchport and cabling should be checked/replaced.
    Firewall enabled?

      No other devices on the same IP, have upgraded all drivers and firmware on the server itself.

      going to try a reboot of the switch as it hasn't been restart for 197 days, if not will try and get an engineer (site is remote) to re-patch to a different switchport.

      firewall is disabled.

        Make sure it is fully patched as well (thinking about the tcp chimney issue a while back).

            what makes this extra weird is that when the user(s) in question email goes down because there pc loses connectivity to the exchange server, i can still ping the exchange server and it can ping me (i am on a different subnet at the other end of a vpn tunnel).

            weird ha?
