A user reports that a server is not accessible. A technician sees the following message on the server: PXE server not found. Which of the following should the technician attempt FIRST to resolve the…

A loose network cable would not cause PXE boot attempts to appear; the error message directly indicates a boot order misconfiguration, not a physical connectivity problem.

The PXE error is related to network boot attempts, not optical media; ejecting a CD-ROM disc would not affect the PXE boot sequence or resolve the underlying BIOS configuration issue.

PXE (Preboot Execution Environment) is a network-based boot method; the error 'PXE server not found' means the BIOS is configured to attempt a network boot before or instead of booting from the local hard drive. Entering the BIOS and changing the boot sequence to prioritize the local disk over the network adapter will allow the server to boot normally from its installed operating system. This is the direct root cause fix and should be attempted before any hardware-level troubleshooting.

Reseating PCI cards addresses physical hardware faults, which are not indicated by a PXE boot error - this is a BIOS firmware configuration issue, not a hardware seating problem.
