- What is Network Stack
- Network Stack enables booting from network instead of local hard drive
- Default enabled on most client computers
- Used by devices without local hard drive or IT professionals for OS deployments
- How PXE Boot Works
- Uses DHCP and TFTP protocols for client-server communication
- Client broadcasts discover packet, DHCP server responds with offer
- DHCP server sends boot server IP and boot file name
- Boot files transferred via TFTP to client for operating system
- Security Considerations
- Network Stack vulnerable to attacks if not used
- Should be disabled unless necessary
- Enables quick OS installations through Windows Deployment Server
- Configuration
- Enabled/disabled through UEFI/BIOS settings
- Located under Integrated NIC option
- Can be set to "Disabled," "Enabled," or "Enabled with PXE"
- Boot order can be changed while keeping Network Stack enabled
