I'm having trouble with a Windows 2008 Server running on Amazon EC2. A few times a day (2-3 times, maybe more), I get an unexpected restart (BSOD), the server reboots and I receive this message: bluescreen event 41 task 63 code 209.
This issue appeared out of the sudden, I haven't change any of the settings.
It seams the error was triggered because of a LAN driver installed on that machine. After an upgrade, the issue was solved.
