I've had a similar problem since upgrading from 2.8 to any of the 2.9 releases; spontaneous reboots after 5-15 minutes. Can't read the "STOP" message on the blue screen but the event viewer reports it as:

The computer has rebooted from a bugcheck. The bugcheck was: 0x000000d1 (0x00000064, 0x00000002, 0x00000000, 0xbfebd6b5). Microsoft Windows 2000 [v15.2195]. A dump was saved in: G:\WINNT\Minidump\Mini052503-04.dmp.

It started happening right after the my first upgrade to 2.9. No other software changes on the computer. Since then, I've updated Win2K & the Java stuff with no luck.

Any thoughts anyone?

Thanks,
Mike
