Servers - Windows NT blue screen procedure on how to obtain a memory dump

Applicable to: World-Wide

To properly support Crashdump, the follow requirements must be met:

• Recovery must be enabled in Control Panel, System, Startup/Shutdown by selecting Write Debugging Information To: and specifying a file name to save the crash information to. This defaults to %SystemRoot%\MEMORY.DMP.
• The paging file must be resident on the system drive and must be at least 1MB larger than physical RAM.
• The system drive must contain free disk space that is at least the size of the paging file.

• Overwrite Any Existing File
• Write An Event To The System Log and/or Send An Administrative Alert
• Automatically Reboot

If Recovery is properly configured when a Stop message occurs, the following events happen:

• The system automatically dumps the RAM contents to the pagefile.
• The computer is automatically restarted (if designated in Control Panel).
• The pagefile contents are written to %SystemRoot%\MEMORY.DMP.

Note: The writing to MEMORY.DMP may take a while to complete depending on the size of PAGEFILE.SYS on the computer. It is important to let it complete uninterrupted. The best way to verify that it has completed is to have selected either Write An Event To The System Log or Send An Administrative Alert, and then waiting for the appropriate notification, either by an event in Event Viewer or an Administrative alert message.

Note: If you system contains more than 1.7GB RAM, please refer to Microsoft article Q173277 for required fixes.
