Did you try running it with DEP turned off?  pwdump (3 IIRC) did the same
thing to a Windows XP machine I was trying to do weak password testing on.
Turn it off temporarily, then try it.

I had this experience with a 2003 server domain controller fully
patched. It killed the lsass process and force rebooted. At the time I
was investigating an unrelated issue and thought that the reboot was due
to the other issue. I never investigated this issue, as it was highly
unlikely that anyone use the LSADump other than me.

Subject: LSADump2 Crashing Systems

In my recent pen-test experience, LSADump2 has been crashing
Windows boxes. I was able to verify this on fully patched
Windows XP and 2003.
In further examination, LSADump2, when executed, killed the "lsass"
process, and with the "winlogon" process still running, the
system was forced to reboot. As far as I know, LSADump2 is
utilizing a DLL injection technique to dump the contents of
LSA secrets.

Question:
1. Has anyone had this experience? If so, is there a safe
method to execute this tool?
2. When I tested LSADump2 on various Windows boxes, not all
fully patched boxes were affected by this issue. What
configuration of Windows is exactly causing "lsass" to fail?

Cheers.
