First Steps to Troubleshoot a Remote System
The following questions are commonly used to troubleshoot high-level
problems in the managed system:
1
Is the system powered on or off?
2 If powered on, is the operating system functioning, crashed, or just frozen?
3 If powered off, did the power turn off unexpectedly?
For crashed systems, check the last crash screen (see "Viewing the Last
System Crash Screen" on page 132), and use console redirection (see
"Supported Screen Resolutions Refresh Rates on the Managed System" on
page 170) and remote power management (see "Managing Power on a
Remote System" on page 128) to restart the system and watch the reboot
process.
