INTRODUCTION
This article describes how to gather more information about a Stop error message. These steps do not always give conclusive answers and may only point you to another problem.



Handling event log messages
Configure Windows to write an event log message with bugcheck information:
 * 1) Click Start, and then click Control Panel.
 * 2) Double-click System, and then click the Advanced tab.
 * 3) In the Startup and Recovery section, click Settings, and then select the Write an event to the system log check box.

An event log message is written to the system log.

The description and format of the event log differs from the Memory.dmp file format, but most of the information is the same. The following event log 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 you are troubleshooting certain types of Stop codes. The meaning of the parameters varies, depending on the type of Stop code.

For information about what the parameters mean, search the Microsoft Knowledge Base for the specific Stop code. (Not all Stop code parameters are covered in the Microsoft Knowledge Base.) To query the Microsoft Knowledge Base, visit the following Microsoft Web site:

http://support.microsoft.com/support

Using Dumpchk.exe to determine memory dump file information
If you use Dumpchk.exe, you can determine all of this information and the address of the driver that generated the Stop message. This information can frequently give you a direction to start troubleshooting. Before you run Dumpchk.exe, make sure that you adjust the properties of the command prompt so that the screen buffer size height is set to 999. With this height, you can 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 parts of the output that are most useful.   MachineImageType     i386 NumberProcessors    1 BugCheckCode        0xc000021a BugCheckParameter2  0x00000001 BugCheckParameter3  0x00000000 BugCheckParameter4  0x00000000

ExceptionCode       0x80000003 ExceptionFlags      0x00000001 ExceptionAddress    0x8014fb84 Not all sections give the same information. The information depends on the kind of Stop code. The information in the example tells you the Stop code (0xc000021a), the parameters (0xe1270188, 0x00000001, 0x00000000, 0x00000000), and the address of the driver that called the exception (0x8014fb84). You can use this address to identify the driver name by using the output from Pstat.exe. Pstat.exe is in the Resource Kit.

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

Using Pstat.exe to identify a driver
Pstat.exe is a Resource Kit utility that gives you information about the processes and drivers that are currently running on your computer. For diagnostic purposes, the most useful information is the list of loaded drivers at the end of the output.

Run Pstat.exe at a command prompt. To pipe the information that you receive from Pstat.exe into a file, use the following command syntax:

pstat.exe >

The following list is an example of the driver list that appears at the end of the output:   ModuleName   LoadAddr  Code    Data    Paged  LinkDate --  Ntoskrnl.exe 80100000  270272   40064  434816 Sun May 11 00:10:39 1997 Hal.dll     80010000   20384    2720    9344 Mon Mar 10 16:39:20 1997 Aic78xx.sys 80001000   20512    2272       0 Sat Apr 05 21:16:21 1997 Scsiport.sys 801d7000   9824      32   15552 Mon Mar 10 16:42:27 1997 Disk.sys    80008000    3328       0    7072 Thu Apr 24 22:27:46 1997 Class2.sys  8000c000    7040       0    1632 Thu Apr 24 22:23:43 1997 Ino_flpy.sys 801df000   9152    1472    2080 Tue May 26 18:21:40 1998 Ntfs.sys    801e3000   68160    5408  269632 Thu Apr 17 22:02:31 1997 Floppy.sys  f7290000    1088     672    7968 Wed Jul 17 00:31:09 1996 Cdrom.sys   f72a0000   12608      32    3072 Wed Jul 17 00:31:29 1996 Cdaudio.sys f72b8000     960       0   14912 Mon Mar 17 18:21:15 1997 Null.sys    f75c9000       0       0     288 Wed Jul 17 00:31:21 1996 KSecDD.sys  f7464000    1280     224    3456 Wed Jul 17 20:34:19 1996 Beep.sys    f75ca000    1184       0       0 Wed Apr 23 15:19:43 1997 Cs32ba11.sys fcd1a000  52384   45344   14592 Wed Mar 12 17:22:33 1997 Msi8042.sys f7000000   20192    1536       0 Mon Mar 23 22:46:22 1998 Mouclass.sys f7470000   1984       0       0 Mon Mar 10 16:43:11 1997 Kbdclass.sys f7478000   1952       0       0 Wed Jul 17 00:31:16 1996 Videoprt.sys f72d8000   2080     128   11296 Mon Mar 10 16:41:37 1997 Ati.sys     f7010000     960    9824   48768 Fri Dec 12 15:20:37 1997 Vga.sys     f7488000     128      32   10784 Wed Jul 17 00:30:37 1996 Msfs.sys    f7308000     864      32   15328 Mon Mar 10 16:45:01 1997 Npfs.sys    f7020000    6560     192   22624 Mon Mar 10 16:44:48 1997 Ndis.sys    fccda000   11744     704   96768 Thu Apr 17 22:19:45 1997 Win32k.sys  a0000000 1162624   40064       0 Fri Apr 25 21:17:32 1997 Ati.dll     fccba000  106176   17024       0 Fri Dec 12 15:20:08 1997 Cdfs.sys    f7050000    5088     608   45984 Mon Mar 10 16:57:04 1997 Ino_fltr.sys fc42f000  29120   38176    1888 Tue Jun 02 16:33:05 1998 Tdi.sys     fc4a2000    4480      96     288 Wed Jul 17 00:39:08 1996 Tcpip.sys   fc40b000  108128    7008   10176 Fri May 09 17:02:39 1997 Netbt.sys   fc3ee000   79808    1216   23872 Sat Apr 26 21:00:42 1997 El90x.sys   f7320000   24576    1536       0 Wed Jun 26 20:04:31 1996 Afd.sys     f70d0000    1696     928   48672 Thu Apr 10 15:09:17 1997 Netbios.sys f7280000   13280     224   10720 Mon Mar 10 16:56:01 1997 Parport.sys f7460000    3424      32       0 Wed Jul 17 00:31:23 1996 Parallel.sys f746c000   7904      32       0 Wed Jul 17 00:31:23 1996 ParVdm.sys  f7552000    1312      32       0 Wed Jul 17 00:31:25 1996 Serial.sys  f7120000    2560       0   18784 Mon Mar 10 16:44:11 1997 Rdr.sys     fc385000   13472    1984  219104 Wed Mar 26 14:22:36 1997 Mup.sys     fc374000    2208    6752   48864 Mon Mar 10 16:57:09 1997 Srv.sys     fc24a000   42848    7488  163680 Fri Apr 25 13:59:31 1997 Pscript.dll f9ec3000       0       0       0 Fastfat.sys f9e00000    6720     672  114368 Mon Apr 21 16:50:22 1997 NTdll.dll   77f60000  237568   20480       0 Fri Apr 11 16:38:50 1997 --         Total          2377632  255040 1696384 By using the starting address in the LoadAddr column, you can match the exception address to the driver name. For example, if you received 8014fb84 as the exception address, the list shows that Ntoskrnl.exe has the nearest load address below the exception address. Therefore, Ntoskrnl.exe is most likely to be the driver that called the exception. With this information, you can search the Microsoft Knowledge Base for known issues that match your situation.
