Routine Description:

    Handle CopyHook operation for the specified service.  Check to see
    if the object involved is shared under WWW/FTP, and if so make sure
    that the alias uses the new directory path or is deleted

Arguments:

    LPCTSTR szService     : Service name
    DWORD dwMask          : Service mask
    UINT wFunc            : Copy handler function (delete, rename, etc)
    xxLPCTSTR pszSrcFile  : Source file
    xxLPCTSTR pszDestFile : Destination file
    int nConfirmMsg       : Confirmation message

Return Value:

    None
