• Symptom: You schedule a chkdsk before rebooting a Windows machine (can be Windows XP or any flavor of Server 2003, possibly others as well) it appears to run through the chkdsk successfully, then reboots again and continues the cycle, continuously running chkdsks on startup, but never getting up to Windows.  Sometimes the Windows splash screen shows, sometimes not.

    Power down and cold boot doesn’t change the behavior.  Attempting to boot into Safe Mode also fails with the same behavior.

    Cause: Unknown, but probably due to a failing chkdsk operation not removing the BootExecute reg value.

    Resolution (some steps borrowed from http://windowsxp.mvps.org/peboot.htm and http://support.microsoft.com/kb/158675):

    1. Create a BartPE boot CD.  You will need the install disk for your exact edition of Windows to do this.
    2. Insert the BartPE CD into the drive, and boot the system from the CD. Once the file loading phase is over, the Bart PE desktop will be visible.
    3. Type Regedit.exe in the prompt, and press Enter. Select the HKEY_LOCAL_MACHINE hive.
    4. From the File menu, choose the Load Hive option. Browse to your Windows installation drive, for example the following location:
    5. C:\Windows\System32\Config\

    6. Select the file named SYSTEM (the file without any extensions), and click Open
    7. Type a name for the hive that you’ve loaded now. (Example: MyHive)
    8. Now the SYSTEM hive is loaded, and present under the HKEY_LOCAL_COMPUTER base hive.
    9. In order to fix the BootExecute value in the loaded hive, navigate to the following location:
    10. HKEY_LOCAL_COMPUTER \ MyHive \ CurrentControlSet \ Control \ Session Manager

    11. Double-click BootExecute and change it’s value to:
    12. autocheck autochk *

    13. After entering the correct data, you MUST unload the Hive. To do so, select MyHive branch, and then in the File menu, choose Unload Hive. It’s important to note that you’ll need to select the MyHive branch first, before unloading it.
    14. Quit BartPE and restart Windows.  The machine should now boot up normally, skipping the chkdsk.

  • If you have WIndows XP SP3 and you try to install the Microsoft hotfix to install the Link Layer Topology Discovery service, you’ll get an immediate error message saying:

    “Setup has detected that the Service Pack version of this system is newer than the update you are applying.  There is no need to install this update.”

    Unfortunately, this may or may not actually be accurate, as the LLTD update is not always installed on computers with XP SP3.  As far as I can tell, this is a known bug in SP3, and MS has been slow to release a LLTD update specifically for SP3.  In the meantime, here’s how to force the LLTD update to run on SP3:

    First, make sure you can see hidden folders:
    1. From any Explorer window (not IE) click on “Tools” -> “Folder Options” -> “View” tab.

    2. Enable the radio button labeled “Show hidden files and folders” and uncheck the “Hide extensions for known file types”.

    Actual Install:
    1. Download the installer file from here or here.

    2. Rename it to something like LLTD.exe (unless you really want to type out “WindowsXP-KB922120-v5-x86-ENU.exe”) and put it in the root of your c: drive.

    3. Go to Start -> Run, and type in “cmd” (without the quotes) and hit Enter.

    4. When the black command prompt comes up, type in “cd c:\” (minus quotes) and hit Enter.

    5. Now type in “LLTD.exe -x:c:\LLTD” (again, minus quotes).  This will extract all the files in to a new folder called c:\LLTD.

    6. Open that folder with an Explorer window, and there will be another folder inside it called “SP2QFE”.  Open that, find the file named “rspndr.sys”, and copy it inside your c:\Windows\system32\drivers directory.

    7. Also in the “SP2QFE” folder, find the “rspndr.exe” and copy it inside your c:\Windows\System32 directory.

    8. Finally in the IP Folder, find the “rspndr.inf” file , and copy it inside your c:\Windows\inf directory.

    9. Now back in the command prompt enter “cd C:\Windows\system32” and then enter “rspndr.exe -i”.  This will actually install the LLTD.

    When it completes, you should get a notice stating that it’s installed. Go to your Network Interface Card and verify that you see Link Layer Topology Discovery.

    Good luck!
