The Internet Information Services (IIS) debug tools are designed to help determine which requests have caused IIS to crash and to log specific information when a request does not respond in an expected time period. This toolkit is made up of 2 main tools: IIS Crash/Hang Agent: tracks all requests as they enter IIS and leave IIS and will log requests that are still being processed if IIS terminates unexpectedly. This tool also allows an administrator to configure a command line to run whenever a request takes too long to respond indicating a potential hang.
IIS Dump: The default command line for gathering information on Hangs; this tool is able to dump many different items at once for root cause analysis investigation. IIS Dump can produce text reports on stacks for each thread in an IIS-related process, dump files for each IIS-related process, dump the Metabase in an XML format file, and provide system DLL version information. This version is the first release on CNET Download.com.
