SUMMARY

This article describes how to gather more information about a blue-screen error message. Note that these steps may not always provide conclusive answers and may only be a symptom of another problem.

MORE INFORMATION

Event Log Messages

  • Configure Windows to write an event log message with bugcheck information. Windows NT Server 4.0 is set to write event log messages by default. Windows NT Workstation is not set by default. To set your system to write an event log message, click to select the Write an event to the system log" check box that is located in the Recovery section of the Startup/Shutdown tab in System properties. This will cause an event log message to be written to the system log.
  • The description and format of the event log differs from the format that is displayed when the computer is writing the Memory.dmp file, but the majority of the information is the same. Below is an example of the event log:
    Event ID: 1001
    Source: Save Dump
    Description:
    The computer has rebooted from a bugcheck. The bugcheck was : 0xc000021a (0xe1270188, 0x00000001, 0x00000000, 0x00000000). Microsoft Windows NT (v15.1381). A dump was saved in: C:\WINNT\MEMORY.DMP.
    This information contains the stop code 0xc000021a and the four parameters. These can be very useful when troubleshooting certain types of stop codes. The parameters will mean different things depending on what type of stop code it is. For information about what the parameters represent, search the Microsoft Knowledge Base for the specific stop code. Not all stop code parameters are covered in the Microsoft Knowledge Base.

Using Dumpchk.exe to Determine Memory Dump Information

If you use Dumpchk.exe from the Service Pack 3 CD, you can determine all of the information that is mentioned earlier and the address of the driver that generated the stop message. This information can often give you a direction to begin troubleshooting. Before you run Dumpchk.exe, be sure to adjust the properties of the command prompt so that the screen buffer size height is set to 999. This height will allow you to scroll back to see the output. Run Dumpchk.exe from the command prompt with the following syntax:
dumpchk.exe Memory.dmp
This is an example of the portions of the output that are most useful:
MachineImageType i386
NumberProcessors 1
BugCheckCode 0xc000021a
BugCheckParameter1 0xe1270188
BugCheckParameter2 0x00000001
BugCheckParameter3 0x00000000
BugCheckParameter4 0x00000000

ExceptionCode 0x80000003
ExceptionFlags 0x00000001
ExceptionAddress 0x8014fb84
Note that not all sections will give the same information. This will depend on the type of stop code. The information above tells you the stop code (0xc000021a) and the parameters (0xe1270188, 0x00000001, 0x00000000, 0x00000000), as well as the address of the driver that called the exception (0x8014fb84). This address can be used to identify the driver name by using the output from running Pstat.exe, which can be found in the Resource Kit.

Dumpchk.exe will also verify that the dump is valid.

Using Pstat.exe to Identify Driver Information

Pstat.exe, a Resource Kit utility, will give you a picture of the processes and drivers currently running on your system. For these purposes, the most useful information will be the list of loaded drivers that appears at the end of the output. All you need to do is run Pstat.exe from the command line. The information given by Pstat.exe can be piped to a file by using the following syntax:
pstat.exe > filename
This is an example of the driver list at the end of the output:

By using the starting address shown under the "Load Addr" column, you can match the exception address to the driver name. Using 8014fb84 as an example, you can determine that Ntoskrnl.exe has the nearest load address below the exception address and is most likely the driver that called the exception. With this information, you can visit the Microsoft Knowledge Base to look for known issues that match your situation.
