\"Too many parameters\" problems

Hi,everybody
I am trying to builder a WDM driver ( a sample in ds2.7) It shows me the following messages. I have no idea why. My OS is win98(not the final release) +DDK98 or DDk2000+DS2.7.It seems the settings problem. I tried to search the solution from this web, but I can not find it.. Can someone help me to solve this problem? Thanks in advance!

With win98+DDK98 or DDK2000+DS2.7+VC6.0 it always shows the following messages when I press the buil button from the DS2.7 menu under VC6.0:

Current DDK Directory = c:\\98DDK

New or updated MSVC detected.  Updating DDK environment....

Setting environment for using Microsoft Visual C++ tools.
Too many parameters
Starting dirs creation....Completed.
DOSKey installed
Bad command or file name
Tool returned code: 0

IF I PRESS THE \"rebuild all\" from VC6.0 build menu. It seems OK.
