请教配置问题

  当前系统:xp2+vc6.0+vs.net2003+win2003ifsddk+ds3.1
 ddk root directory:c:\winddk\3790
当编译vdwlibs时出现如下错误:
fatal error C1083: Cannot open include file: 'ntddk.h': No such file or directory
Invalid wdm.h! Check include path.  wdm.h should be in the DDK directory defined by $(WDM_INC_PATH).

请问怎么办?
