DDK Build problems

Hi all,

I have been building drivers and DDK samples on Win2k with Win2k DDK and IFS
kit.
After installing some other third party tools the builds stopped working with
the error
output below:

BUILD: Exec of ‘nmake.exe /c BUILDMSG=Stop. -i NTTEST= UMTEST= CHECKED_ALT_DIR=1
NOLINK=1 NOPASS0=1 386=1’ failed - errno = 0

Does anyone have any idea what this means? Is it that the environment has
changed such that
it cannot exec a child process for nmake.exe. Nmake.exe is on the path and is
part of the VC 6.0
tools. I cannot locate any information about what may have changed in the
environment so
that I can reset it.

Thanks
Steve
