求助！sfilter编译问题

我下载了Coolice提供的sfilter for XP&2000,在W2000，VC环境下编译出现以下问题：

--------------------Configuration: sfilter - Win32 free--------------------

BUILD: Compile errors: not linking e:\\wdmbook\\sfilter\\sys directory

    2 files compiled - 3 Errors

sfilter.sys - 3 error(s), 0 warning(s)
==========================================================
其它的情况是：我把NTIFS.H拷到文件的当前目录下，包含的头文件是 #include \"ntifs.h\"
   #include \"ntdddisk.h\"

望高手指教!
