    This output does not indicate confusion about the path. It just means
    c:\WINNT\system32\winlogon.exe, and it is the normal path reported for
    Winlogon by fport and other utilities.
    
    As to why it is reported like that, here's a quote from
    http://msdn.microsoft.com/msdnmag/issues/02/06/debug/default.aspx
    " For some reason, the path names returned by GetModuleFilenameEx or the
    TOOLHELP32 module functions are very strange; they don't follow the Win32
    standard. For example, smss is retrieved as "\SystemRoot\System32\smss.exe";
    "\SystemRoot must be replaced by the actual name of the Windows folder. For
    winlogon, you get "\??\C:\WINNT\system32\winlogon.exe," which should be
    translated into "C:\WINNT\system32\winlogon.exe." The \??\ prefix might be a
    leftover from the Windows NT namespace root, essential in kernel mode, even
    though it is rarely used at the Win32 programming level. "
    
    So don't worry about the path reported by fport. The TCP 109 looks rather odd,
    though. I don't know the answer to that.
