SoftICE problems after installation of service packs or hot fixes



I just added a service pack (or used automatic updates via Windows) and SoftICE is not working correctly.


Any service pack or hot fix (Result of using auto update) can possibly change ntoskrnl.exe. When this changes it makes it difficult for SoftIce to find operating system information.

There are often several ways to fix this.

  1. Uninstall the service pack or hot fix.
  2. If the version is 2.7 or higher then use this file in place of the existing one located in system32\drivers directory.
  3. Try what is called the "ntsymbols" trick as described below.
    1. Create a correct NMS file for ntoskrnl. See "Translating system files" below.
    2. Place the NTSYMBOLS=ON keyword on a separate line in winice.dat.
    3. Add the symbols to the list of symbols to load at start. See "Adding files to start" below.

That should solve nearly even problem encountered with a hot fix or service pack.


  1. Be sure you have the correct symbols for your service pack and OS from the Microsoft web site or from the hot fix download zip file.
    Note: The example below is for ntoskrnl but the steps should be done on any system file you plan on translating.
  2. Find the correct ntoskrnl.exe for you machine. To do this right click on ntoskrnl.exe and select properties. Then select the version tab and then the original file name view.
  3. If the original file name was something other than ntoskrnl.exe then copy and rename the copy of ntoskrnl back to its original name.
  4. Copy the ntoskrnl.dbg (or pdb) that matches the original ntoskrnl.exe into the same directory as the exe.
  5. Open SoftICE symbol loader.
  6. Open the ntoskrnl.exe and translate the executable.
  7. If the exe was renamed due to the original file name then rename the resulting nms file back to ntoskrnl.nms
  8. Add ntoskrnl.nms to your list of symbol files to load at start using the softice init settings dialog.


  1. Open symbol loader.
  2. From the edit menu choose "Softice initialization settings".
  3. Go to "symbols" in the left side tree.
  4. Use the add button and navigate to the nms file that you made and add it to the list.
