Software problems
The best sources of information for software problems are the operating system and application software
documentation, which may also point to fault detection tools that report errors and preserve the system
configuration.
Other useful resources include HP Insight Diagnostics (on page 48) and HP SIM. Use either utility to gather
critical system hardware and software information and to help with problem diagnosis.
Operating system problems
Operating system locks up
Action: Scan for viruses with an updated virus scan utility.
General protection fault occurs
A general protection fault, or general protection error, occurs when the Microsoft operating system
terminates suddenly with an error, including but not limited to:
• Miscalculating the amount of RAM needed for an allocation
• Transferring execution to a segment that is not executable
• Writing to a read-only or a code segment
• Loading a bad value into a segment register
• Using a null pointer
A GPF is immediately identifiable by a blue screen with white text, and the text may contain information that
identifies the problem.
Action:
• Remove any newly installed software or hardware to verify that they are not the cause.
• Boot the server in Safe Mode or Last Known Good Configuration.
If neither of these actions resolve the problem, contact an authorized service provider. For more information
about debugging tools or specific GPF messages, refer to the Microsoft website
(http://www.microsoft.com/whdc/devtools/debugging/default.mspx).
Errors are displayed in the error log
Action: Follow the information provided in the error log, and then refer to the operating system
documentation.
Problems occur after the installation of a service pack
Action: Follow the instructions for updating the operating system ("Operating system updates" on page 90).
