Assistance analyzing a crash dump (Server 2008)

Hello, I was hoping someone could just verify what I think I'm seeing here in crash dump of one of our systems.  The server crashed unexpectedly and judging from the dump, it looks to me like someone was logged on there and went on to kill SMSS in task manager, thus causing the crash.  I have attached some of the pertinent dump info below.

Thanks!

CRITICAL_OBJECT_TERMINATION (f4)
A process or thread crucial to system operation has unexpectedly exited or been
terminated.
Several processes and threads are necessary for the operation of the
system; when they are terminated (for any reason), the system can no
longer function.

Arg1: 0000000000000003, Process
Arg2: fffffa80333eb130, Terminating object
Arg3: fffffa80333eb410, Process image file name
Arg4: fffff80001fd9470, Explanatory message (ascii)

i would have to agree; that's what it looks like
as if someone terminated that system process
was it just this one time or has it happened more than once?

It was just this one time, but I just wanted to make sure I had root cause down.

The SMSS.exe file is always located in the C:\Windows\System32 folder.

It is the Microsoft Windows Session Manager Subsystem.

If you find that there is an smss.exe located in another folder, then it is probably malware (either a virus, spyware, trojan or worm).

Malware programs try to look like legitimate computer processes and the smss.exe trojan is one of them.  

Go to Start Search, and type in smss.exe and look at the file that comes up.

If it is in the Windows\System32 folder then it is not a virus or spyware.

Are you seeing any issues with your computer or is the only error in the system event log?  

When do you experience this error?

Have you ever had this error before or is this the first time?

What programs are open and running when you see this error?

yeah i've done this at home just to play with - seeing what happens when you kill one of those processes either with task manager or sysinternals tools and have had that error occur

and this isn't malware.  the link referenced shows an application crash while this is a stop code.  if it was malware a stop code 0xF4 wouldn't be generated like that
