Ok, admittedly, this is an unusual configuration. But in the event you find yourself needing to download ISO images from MSDN in a Windows 2003 OS running in a VMWare virtual machine, beware.
The File Transfer Manager performs a brief file validation at the end of each download. On my virtual Windows 2003 machine, this validation step maxed the CPU and RAM. Within about 5 seconds, my virtual machine locked up and my host machine blue screened--forcing a reboot of the host machine.
That's a serious memory leak.
