Microsoft's free memory test utility

I had no idea Microsoft provided this free memory test utility. I guess I'm too much in the OS X world these days. Many thanks to "enthusiast" for the pointer to this a set of similar test utilities.

Microsoft Online Crash Analysis - windiag

The Windows Memory Diagnostic tests the Random Access Memory (RAM) on your computer for errors. The diagnostic includes a comprehensive set of memory tests. If you are experiencing problems while running Windows, you can use the diagnostic to determine whether the problems are caused by failing hardware, such as RAM or the memory system of your motherboard. Windows Memory Diagnostic is designed to be easy and fast. On most configurations, you can download the diagnostic, read the documentation, run the test and complete the first test pass in less than 30 minutes.

To run Windows Memory Diagnostic, you must reboot your computer with the disk or CD-ROM on which you installed Windows Memory Diagnostic in the drive. After the reboot, Windows Memory Diagnostic will load and its interface will appear. After loading, the first test pass will begin, using the default standard test suite, and continue until complete, unless Windows Memory Diagnostic is either paused or exited. Once the first test pass is complete, Windows Memory Diagnostic will begin a second test pass using the same settings as before. Windows Memory Diagnostic will continue to run test passes until you exit...

I'm looking at this because my "possessed" (really, it is) corporate Dell Latitude (XP SP2 +) just gave me an error message on a huge file copy that was supposed have been fixed in Windows 2000:

You May Not Be Able to Copy Large Files on Computers That Are Running Windows NT 4.0 or Windows 2000

...Cannot copy [filename]: Insufficient system resources exist to complete the requested service...

Yes, this could be due some mysterious corporate monitoring software; many corporations are layering loads of cr*p atop an already unstable XP/antivirus environment, thereby taking XP into new realms of emergent behavior.

My money though is on flaky hardware. I'll try that Windiag and the Dell test suite that comes with their restore DVD.
