We need to run a kernel dump (we are using livekd) on a secure Status server that we CANNOT open up to the internet in order to download symbols from Microsoft's symbols server. We have download the symbols to an identical Stratus server and ran the livekd kernel dump successfully.even moving the symbols directory/path around at will. Not picking up thread can be several issues, like bobbin is miswound, bobbincase isn't snapped in properly, you're using the wrong type bobbin, machine isout of time, needle is bent or burred, machine is dirty and in need of dustbunny eviction and a little oil but most of the time the issue is once againmisthreading: sewing machine needles have.

What You Need
- The Windows Server 2008 VM handed out by your instructor.This project can be done on other machines, including Windows 10, butfirst you'll need toinstall Windbg and LiveKD
Purpose
Practice using simple WinDbg commands.We'll useLiveKd, a utility that makes some limited kerneldebugging possible with a single computer. LiveKdis read-only -- you can look atkernel processes and data structures, butcannot modify a running system or use breakpoints.Using LiveKd
In a Command Prompt window, execute this command:When Livekd starts, it asks youwhether to set the _NT_SYMBOL_PATHautomatically, as shown below.Type y and press Enter.
Livekd asks 'Enter the folder to which symbols download'. Press Enter to accept the default option.
Windbg launches, as shown below.
This is a strange combination of a GUI andcommand-line, like the other debuggers we've used.Commands are typed into the box at the bottom and the resultsappear in the large top pane.
At the bottom of the Command window,in the command bar, execute this command:
You should see the 'kd> !process' command,and its output, showing informationabout the windbg process, includingits Cid number,as shown below.When I did it, the Cid was 0b14 in hexadecimal,which is 11*256 + 16 + 4 = 2836.
Viewing Processes with Task Manager
At the bottom of the desktop, point to an unused portionof the taskbar and right-click. Click'Task Manager'. In Task Manager, clickthe Processes tab.Find the windbg process, and its PID,as shown below. It should match the Cid fromWindbg.
Close Task Manager.In Windbg,at the bottom of the Command window,in the command bar, execute this command:
You see a long list of all processes,as shown below.Online Help
At the bottom of the Command window,in the command bar, execute this command:You see a brief help message about the'process' command,as shown below.At the bottom of the Command window,in the command bar, execute this command:
You see a much more complete helpwindow,as shown below.Listing Modules with lm
At the bottom of the Command window,in the command bar, execute this command:A long list of all loaded modules scrollsby.Scroll back to see the lmcommand you entered, and the first fewloaded kernel modules, as shown below.
Scroll down to find the module namednt, as shown below.It's easy to spot because it'e one of thefew modules that shows a Symbols path.
This is Ntoskrnl, the main kernelmodule.
Viewing Memory
Here are some commands that display memory:dd
Display dwords (32-bit values)da
Display ASCII textdb
Display Bytes and ASCII textdt
Display Type: Information about a variable, data type, or structure
dd nt
You see the first several bytes ofNtoskrnl.exe, as shown below.
This may be more familiar inASCII.
In WinDbg, execute this command:
da nt
You see the characters 'MZ' --theyare at the start of every EXE file.
In WinDbg, execute this command:
db nt
This displays the bytes on the left,and the ASCII on the right.Now you can see the message'This program cannotbe run in DOS mode Empire total war mac download. ',which appears at the startof many EXE files.
Examining Symbols
The x command examinessymbols, which include function names.Searching for Functions
In WinDbg, execute this command:x nt!*
This finds all the functions in Ntoskrnl.There are a lot of them,as shown below. It may take a minuteor so to show them.
In WinDbg, execute this command:
Livekd Could Not Resolve Symbols For Ntoskrnl.exe 5
x nt!*Create*
This finds all the symbols in Ntoskrnlthat contain the word 'Create'.
There are a lot of them, too.
In WinDbg, execute this command:
x nt!*CreateFile*
This finds all the symbols in Ntoskrnlthat contain the word 'CreateFile'.
There are only about ten of those,including 'nt!NtCreateFile',as shown below:
Unassembling a Function
In WinDbg, execute this command:u nt!NtCreateFile
Livekd Could Not Resolve Symbols For Ntoskrnl.exe 1
This shows the first few bytes of thefunction, disassembled,as shown below:
![Livekd Livekd](/uploads/1/1/8/8/118814566/889511662.jpg)
To see more of this function,it helps to use theWinDbg Disassembly window.
If the Command window is maximized,make it smaller.
From the WinDbg menu bar, clickView, Disassembly,as shown below:
In the Offset bar at the top,enter
nt!NtCreateFile
This shows the assembly code beforeand after the start of the NtCreateFilefunction. Using the up-arrowand down-arrow keys, you canscroll to see the entireassembly code for thisfunction, as shown below:
Viewing Type Information for a Structure
In WinDbg, execute this command:dt nt!_DRIVER_OBJECT
This shows the first few lines ofa driver object structure, whichstores information about a kerneldriver,as shown below. Notice the DriverStartpointer--this contains the location of thedriver in memory.
Challenge 15a: Function Name (5 pts)Find the Windows kernel function thathas a name fitting this pattern:two characters, RegistryKey,then six more letters, like this: Use the formbelow toget your points. |
Challenge 15b: Beep (10 pts)Disassemble the Beep module,near its DriverEntry.Find thehexadecimal valuescovered by the green boxin the image below. Use the formbelow toget your points.

I'm having trouble loading the symbols for the ntoskrnl.exe into windbg.
Livekd Could Not Resolve Symbols For Ntoskrnl.exe 7
I've got the latest symbols installed on my machine from the web (base 2k
symbols + 2kSP4 symbols). Since I have a MP machine I renamed ntkrnlmp.* to
ntoskrnl.* in the symbol files.
The log that follows is the output from the windbg screen. The first part
shows that windbg looked to the web for the symbol information (since I'd
used !symfix in a previous session and saved it). The second part shows
windbg trying to reload symbol information form a local path to my copy of
the debug symbols.

I can't seem to get a stack trace without loading the symbols for ntoskrnl.
Any ideas?

(Any reason why the symbol files ntkrnlmp.dbg is 99kb while the ntoskrnl.dbg
is 1.7MB?)
is 1.7MB?)
Thanks for your help.
