Diagnostic software for Intel(R) Pro/100 VE Network connections adaptor

                                                              Hi Everyone,

 On my Dell Dimension 4550 WinXP Pro Sp3 computer , I have a preinstall Intel(R) Pro/100 VE Network connections adaptor . And it came with some Diagnostic software also . With the latest version of the software being only assessable thru Device Manager .

 Once when I did a repair install I had to download a driver/software package for my computer . And reinstall the drivers and software.

  Now I have noticed that the Diagnostic software is no longer available thru device manager . I don't know if the Diagnostic software is not compatible with the SP3 update , or something else happened to it. I did try to reinstall my drivers and Diagnostic software , but the driver reinstall worked , but the Diagnostic software was still not available.

  So I would like to ask what steps I can take to fix this problem ( no diagnostic software ) , or perhaps re -download some more driver/Diagnostic software install files, in case the one stored on my computer became corrupt ?

Thanks .
