Dedicated Dump File In Windows Server 2008

by [Published on 23 June 2010 / Last Updated on 31 July 2009]

This article explains a new feature of Windows Server 2008 called Dedicated Dump File.

Memory dump files are generated when a system is crahsed. These dump files are used by the administrators or product team to troubleshoot further as to know what caused the error. These dump files are generated on the C: drive and there is no way to change this location in previous versions of Windows. Windows Server 2008 introduces a new feature called Dedicated Dump File. This new feature allows a dedicated dump file to be located on any of the volumes and not just the C: drive which is the boot volume.

You need to use the following registry on computers running Windows Server 2008 to configure this feature:

  • KEY Name: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl
  • Entry Name: DedicatedDumpFile 
  • Data Type: REG_SZ 
  • Value Name: full path of the file location (e.g. D:\Dumps\Memory.DMP)
