    My Vista Business SP1 laptop wireless networking stopped working on my
    Lenovo ThinkPad T400. The problem boils down to an

    error starting the "Extensible Authentication Protocol" service. When
    I try to start the service, I get a generic error:


    Windows could not start the Extensible Authentication Protocol service
    on Local Computer.

    Error 2: The system cannot find the file specified.

    I tried the two solutions I found on the net but neither resolved the
    problem (wireless doesn't work, EAP service won't


    Start Service Wired AutoConfig Properties

    Start hidden service ndisuio

    According to the registry key
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EapHost the dll
    for this service is

    "C:\Windows\System32\eapsvc.dll". The file exists. When I open it in
    Dependency Walker it shows a warning for two files:

    Warning: At least one module has an unresolved import due to a missing
    export function in a delay-load dependent module.


    c:\windows\system32\IEFRAME.DLL (7.00.6000.16386)

    Has errors--functions labeled #160, #159, and #141, #165, #167, and
    #142 show up as "Not Bound".


    c:\windows\system32\SHLWAPI.DLL (6.0.6001.1800)

    Has one error, function #467 shows up as "Not Bound".

    Are there newer versions of these files? What updates do I need to
    install to get them? I have no idea why this service

    suddently stopped working--no updates that I recall and no software

    Any other suggestions as to what is wrong or what I should look into?
