Steps to install debugging tools:

1. Go to http://www.microsoft.com/whdc/devtools/debugging/installx86.mspx and download the latest version of debugging tools for windows (32 bit). This setup will install WinDbg which is used to study the crash dumps
   
   
2.  Install User Mode Process Dumper from http://www.microsoft.com/downloads/details.aspx?FamilyID=E089CA41-6A87-40C8-BF69-28AC08570B7E&displaylang=en&displaylang=en This will create the folder - C:\kktools
   
   
3. From, C:\kktools\userdump8.1\x86, click setup.exe. This will create the folder - C:\WINDOWS\system32\kktools

Steps to monitor a crashing process:

1. Go to Control Panel and click on "Process Dumper"
2. Click on New to add the process for which you need the dump. For example, jdenet_k.exe

• Enable "All Exceptions"
• Select "Monitor Process Exit" and set "MiniDump Type" to "Complete"
• Click OK and Apply.

Steps to enable/disable dump logging using gflags:

1. Go to C:\Program Files\Debugging Tools for Windows and type the following command:
   
   Gflags /p /enable <crashing executable name.exe> i.e. gflags /p /enable jdenet_k.exe
   
   To verify that gflags has enabled page heap verification, use the following command:
   
   gflags.exe /p
   
   
2. Reproduce the issue and send GCS the crash dump stored in the location, C:\crashdump
