    I saw a previous topic similar to the problem I am encountering where you asked them to post answers to the following questions.  I followed the steps in below and post the results.  My problem is that on my Dell laptop (Vista) my network connection stopped working and the error message: connection status : Unknown.   The dependency service or group failed to start-  and when I hover over the icon in the tray (which has a red cross through it).  I have tried various solutions found on the web but nothing has helped.   I am hoping that from the info below someone might be able to help me solve this problem.

    1.   Run Command Prompt as administrator. Type “nslookup www.microsoft.com” (without quotation marks). Let me know the result.
    Response:  Uknown can't find ww.microsoft.com: No response from server

    2.   Run Command Prompt as administrator. Type “ipconfig /all” (without quotation marks). Let me know the result.
    copied below

    3.   Run Command Prompt as administrator. Type “ping (the IP address of Default Gateway)” (without quotation marks). Let me know the result.
    Response:  Unable to contact IP Driver, error code 1753

    Hi,

     

    First, please perform System Restore to get back to the state which the issue didn’t occur.

     

    If the issue persists, please go to perform System File Checker to scan your system for missing/corrupt files.

     

    You may also try the following steps:

     

    WinSock and TCP/IP Refresh

    --------------------------------
    1.     Click the Start Button, type "cmd" (without quotation marks), in the search result list, right click on Cmd.exe and select Run as administrator.

     

    Note: If you are prompted for an administrator password or confirmation, type your password, or click Continue.

     

    2. Type netsh winsock reset  in the Command Prompt , and then press the Enter key.

    3. Do the same processes for refreshing the TCP/IP just replace the typed command with.

    netsh int reset   press Enter

    ipconfig /flushdns    press Enter

    4. Restart your Computer.

     

    Regards,

    A Vista Business laptop was failing DNS and DHCP client functions.  Setting a fixed IP on the interface got around the DHCP problem, but DNS did not work.  NSLOOKUP would always fail with a "no response from server".  After many hours of blind alleys, found your post and now have netsh tutorial underway. 

    I was ready to reinstall Vista and this saved my bacon.  Thanks.

    All I needed was netsh winsock reset.
