SYMPTOMS
Crash dumps from some Compaq computers might cause the Microsoft Windows
Debugger, WinDbg.Exe 5.0.1719.1, to crash.
CAUSE
Some Compaq systems install a tool called CPQDbg.exe. This tool generates
user-mode application crash dumps. In some cases, the User.dmp generated by
CPQDbg.exe is corrupt. When you use WinDbg.exe versions 5.0.1719.1 or
earlier to analyze this dump file, it might crash.
CPQDbg.exe is a middleware tool that is installed in Compaq's Insight
Manager (CIM) software on some Compaq systems. CPQDbg.exe is located in
%SystemRoot%\System32\Cpqdbg.exe on some Compaq servers. When CIM is being
installed, it reads the value found under AEDebug\Debuggers. Then it writes
this value to a key under HKLM\System\CurrentControlSet\Services\CPQMgmt
called "Apptrap". CIM then replaces the existing AEDebug\Debugger string
with the CPQDbg string. When an application crashes, this CIM software
tries to generate an SNMP trap to forward to the CIM Management Console. It
then passes the fault to the debugger listed under the Apptrap value. For
Windows NT, the default debugger is normally Dr. Watson, DRWtsn32.exe. In
some cases, CPQDbg interactions create a corrupt dump file.
RESOLUTION
If you have installed CPQDbg.exe and dump files are not being generated
properly, uninstall CPQDbg.exe. Restore DRWtsn32.exe as the default Windows
NT debugger as follows:
- At a command prompt, navigate to the directory containing DRWtsn32.exe.
- Type the following text:
STATUS
Microsoft is researching this problem and will post new information here in
the Microsoft Knowledge Base as it becomes available.
