Need Help in the DeBugging Tool Instructions

By Route44
Mar 19, 2007
  1. I took the archived advice here and downloaded and installed Microsoft's Debugging Tool. I also followed the instructions on how to read a minidump from major Geeks. Their instructions are in black and my responses are in blue. Here is where I become confused on what to do:

    Once you have downloaded and installed these tools, go to start, all programs, Debugging Tools For Windows, Windbg. Once you open Windbg, you will presented with a blank screen. Click on File, Symbol File Path. Here you will enter the symbols path. Symbols are needed to effectively debug.

    I did this with no problems.

    The path will be:

    SRV*c:\symbols*http://msdl.microsoft.com/download/symbols

    Enter in this path and click OK.

    I did this, too, with no problems.

    Now, go to File, Save Workspace so that your symbols path is saved for future use.

    Ditto.


    Now what you want to do is locate your memory dumps. They are usually located in %systemroot%/minidump (in my case C:/windows/minidump).

    I found my memory via Run and %systemroot%/minidump

    If you notice, they are usually named the date, and then a -*number* to indicate the order of minidumps that day. My example is called Mini061904-01.dmp (it happened today).

    I understand.

    Inside of Windbg, go to File, Open Crash Dump and load the file. You will get a message to save base workspace information. Choose no.

    This is where I become confused because when I go to File it lists a bunch of folders but I see no way loading the file to the Open crash Dump. What am I missing? Thanks

    Name the crash dump file(s) folder a name you can remember. I use the posters nickname, or part of his nickname. I download and extract the crash dump files into the folder. Put a shortcut of WINDBG on your taskbar. While you are still in TechSpot, go down to the WINDBG shortcut and open it. Select the crash dump folder and open it using "Open Crash Dump". Point to the crash dump file folder. Select each minidump file, one at a time. You will have to close WinDBG after each crash dump is debugged, and reopen it for the next minidump file

    I apologiz ahead of time if I am not to place all this information but this is what I got from my minidump. Is this pointing to my Sunbelt Kerio Firewall? Iused to have crashes with their earlier versions which someone here read for me and pointed to Kerio. Supposedly the newest version of this firewall is much more stable. The problem I just received this minidump just yesterday. It hasn't even been a week.

    Delete the current version of Kerio, and make sure that you have all the MS Updates for XP, SP2 installed. Mind you, there's nothing wrong with using Kerio, we are just doing this to see if the crashes stop or change... If your system is stable, you can reinstall Kerio, and all should be good

    I appreciate the replies. The thing is with Kerio that this is my third version of their product. I even saved the emails from their Tech Support that admitted that in their earlier versions that BSODs was an occuring problem

    1. I checked my hardware and drivers and they are all compatible.

    2. I have all updates installed for Windows SP/2.

    3. I know several people online who have had the same issues and it disappeared once they uninstalled Kerio.

    So, Tmagic650 what does my information tell you from my minidump?

    And meet the new boss, same as the old boss. The only difference between the two is the first one I listed earlier was 0x0A Stop Error the second was 0x0D Stop Error, but I think both point to Kerio.

    T, again, thanks for the reply and the help. I really want this firewall to work because it does everything I ask and is non-intrusive unlike ZA. But these BSODs are rediculous. The two minidumps that I posted here and you interpreted were from version 635, the third and most recent version I tried. Yet I still get the BSoDs. I've cleaned out all of the firewalll and reinstalled. The only issue now is that it is a trail version of 635 and I can't seem to find where it will allow me to upgrade to the full verion or at least let me put my purchase code in to bring it to a full version. i am still within a years time of free upgrades. At this point I don't have NIPS or HIPS.

    Now they have a version 734. I am wondering if I should just go ahead and install that instead.

    By the way, how did you know it was a driver problem for Kerio? I could read my minidumps but I could not know it was specifically a Kerio driver problem.

    Tmagic650 TS Ambassador Posts: 17,244   +234

    Ok Route44,
    I took fwdrv.sys and inserted into a Google search... try this yourself. Did you try the Kerio reset tool in the link I provided?
     
  10. Route44

    Route44 TechSpot Ambassador Topic Starter Posts: 11,966   +70

    Yes, I used the link you provided and downloaded and installed the tool. I don't know how you found it because when you go to Sunbelt's website I find it difficult, if not impossible, to find these tools links.

    Another person at Wilder's Security Forums was able to link me to Sunbelt's tool to completely clean their SKPF from your system. But, again, I don't find it on their website. Could be though I am totally blind! ;)

    The thing I like about the Wilder's Security forums, which are the official forums for Eset's NOD32 anti-virus product is that it contains the only active and very informative, as well as helpful, Firewall forum that I have come across on the 'net.

    Oh, yes, before I forget, I was able to register my product and I am good to go up to September 27th.

    By the way, do any trout fishing in Montana (yes, i checked your public profile)?

    Tmagic650 TS Ambassador Posts: 17,244   +234

    So are you good to go with the BSOD's now? I'm not much into fishing... Google is a powerful tool if you have enough patients to look through all the links
     
  12. Route44

    Route44 TechSpot Ambassador Topic Starter Posts: 11,966   +70

    Yes, I think I am okay at this point. I'll see if another BSOD occurs under version 635. If it happens I'll know what to look for in the Minidump and I have no problem Googling and going through the links. I didn't realize I could do something as simple as Googling fwdrv.sys and get my answer. I thought one needed a strong background in tech knowledge in order to read it.

    By the way, here is latest 744 version from Sunbelt. I don't know what it all means but I certainly took notice of the Crash fixes at various points:

    This is taken from the "readme".

    * Corrected issue in which registration fails when firewall is enabled.
    * Significant improvement in network performance when web filtering is enabled.
    * Enhanced Process Injection prevention to prevent code inject attempts into Windows system DLLs.
    * Corrected numerous application crashes in the firewall service.
    * Corrected various crashes in assist.exe
    * Corrected issue in which setting password and checking for update does not cancel authentication form.
    * Corrected issue in which binary data appeared in logs.
    * Significant improvement in product stability.
