question about the target OS build version

NTFSD
1

Hi All,

I am just starting to use Windbg for the kernel mode debug. My host machine
is Windows XP SP1 and my target machine is Windows 2000 SP3. Is it necessary
to install the checked-debug version of Windows 2000 on the target machine?
I tried to debug a sample driver sfilter from Microsoft IFS Kit. There is no
any output debug message from the sfilter showed on windbg screen. Your any
suggestion is appreciated.

You do not need a checked version of the OS to do debugging.

By default SFILTER does not do any debug output. It does have an
internal variable (called SfDebug) which controls the debug output.
When SFILTER loads it sets the state of this variable from “DebugFlags”
in the sfilter service definition in the registry.

You could also change the state of this variable from the debugger.

Thanks to Neal.
I mis-set the variable SfDebug by interger 8. It should be 0x00000008.

No, not necessary.
