    I have a computer on my network, that keeps losing its network connection.

    figure out the problem... It happens daily, and is getting frustrating.

    Thank you

  2. Hello Lfheb,

    Thank you for posting to the SBS Newsgroup.

    I am sorry but from your description, I cannot have a clear image what
    exact issue you are experiencing. In order to supplement your description,
    I need your help to gather the following information:

    1. Please explain in detail "Computer logging itself off network".

    c. Client can connect to the SBS 2K3 Server, but cannot access the

    2. In your post, you mentioned "It's running XP (along with all others
    except 2 running 2000)". Are all problematic client workstations running
    the Windows XP Operating System? Have they applied Windows XP SP2?

    3. On one of the problematic client workstation, run "eventvwr" (without
    quotation marks), check whether there are any errors. If yes, double click
    it, click the Copy button and paste the full content to the Newsgroup.

    4. When did the issue occur? Did you have this issue before? Did you make
    any changes or install any software/updates recently?

    5. How many NICs have been installed on the SBS 2K3 Server?

    6. Do you have ISA Server installed? If yes, is it ISA 2K or ISA 2K4?

    7. What is the Network Topology? For example:

    {Internet} {NIC1} {SBS 2K3 + ISA} {NIC2} {In LAN}

    8. On one of the problematic client workstation, open a command window,
    type "ipconfig /all" (without quotation marks). Type the result to the

    Perform the same steps on the SBS Server and type the result to the

    9. From one of the problematic client workstation, can you ping the SBS
    Server by name and IP address?

    For your information: please check the following settings to confirm your
    network configuration.

    On SBS server:

    External NIC:
    IP: assigned by your ISP or your hardware router
    Gateway: your ISP or your Hardware router IP
    DNS: SBS INTERNAL NIC IP as the only entry

    Internal NIC:
    IP: Fixed IP
    Gateway: None
    DNS: SBS INTERNAL NIC IP as the only entry

    On workstation:
    IP: Assigned by DHCP on SBS
    Gateway: SBS internal NIC IP
    DNS: SBS INTERNAL NIC IP as the only entry

    Please take your time to perform the steps and gather the information for
    research. If you have any updates, please feel free to let me know. I am
    looking forward to hearing from you!

    Best regards,
