RE: LSADump2 Crashing Systems

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.
