Cannot Logon - WGA Validation RRS feed

  • Question

  • I have a client using a dell dimension 4300.  One year and 1/2 ago her machine stopped letting her logon.  I brought her machine and her original cd and reloaded the computer.  About 6 months later - the same thing happened - I was out of town - she took it to another tech who reloaded her machine again.  Then 2 months after that - the message came up again.  I tried to call Dell - out of warranty of course - then called Microsoft who wanted $$ to assist me - so I hung up.  I did find a posting that allowed me to fix it - but don't remember what I did at the time.

    Guess what - she called again Yesterday - can't logon on same thing - this copy of windows is not genuine.  I have no idea what might be causing this to occur.  She is a little old lady and does not add hardware, software, or anything unusual.  If you have any ideas - please post asap. 

    I did run the diagnostic last time - but will visit her this morning to try to get her access.  Any ideas????

  • Good Morning Pcdr,

    Please follow the steps outlined below as it could either resolve your issue or, if need be, provide us with additional information to determine the cause of this issue.


    1.      Ensure you log onto the computer experiencing the issue with “Administrator” rights.

    2.      Next we would like to confirm that you are running the most current version of the Genuine Advantage control on your computer. In order to do this please follow the below link and choose the “Validate Windows” option.




    If the above steps did not resolve your issue lets continue with the steps below.

    If you could also please follow the steps outlined below, the diagnostics Web Site will attempt to resolve the validation errors you are experiencing with Windows.


    Next follow the on-screen prompts to resolve the issue if any of the checks at the above site fail. If, after attempting to resolve the issue as per the instructions on the above site fails, please refer to the link below and run the MGA Diagnostics tool:




    You will be prompted to either “Run” or “Save” the tool. Choose to “Run” the tool and follow the on-screen prompts. You will receive an “Internet Explorer-Security Warning” dialog box for the “Windows Genuine Advantage Diagnostic Tool”; you must choose to “Run” this tool when prompted.


    Once you are presented with the Diagnostics tool choose “Continue” to run the diagnostic report. If the “RESOLVE” button is available after running the diagnostics, please click “RESOLVE” to allow the diagnostic tool to attempt a repair.


    1.      After running the MGA Diagnostic tool, click on the “Windows” tab and then click on “Copy”.

    2.      Please return to this post and “Paste” the results here for additional review.


    Step 2 is to look on the computer itself, in the documentation you received with the computer or with your retail purchase of Windows to see if you have a Certificate of Authenticity (COA).  If you have one, tell us about the COA.  Tell us:

    1.  What edition of Windows XP is it for, Home, Pro, or Media Center, or another version of Windows?

    2.  Does it read "OEM Software" or "OEM Product" in black lettering?

    3.  Or, does it have the computer manufacturer's name in black lettering?

    4.  DO NOT post the Product Key.

    Not sure what to look for?  See this page for reference:  http://www.microsoft.com/resources/howtotell/en/coa.mspx


    NOTE: The data collected with the Genuine Diagnostics Tool does NOT contain any information that can personally identify you and can be fully reviewed, by you, before being posted.

    Thank you,
