PC 1 is statically assigned the IP address 192.168.1.1. The ipconfig output for Server 1 shows it is also using the same static IP address, creating a duplicate IP address conflict on the network. As a client workstation, PC 1 should be configured to receive its IP configuration from the network's DHCP server, which will assign it a unique address and prevent conflicts.

The ipconfig /all output for PC 2 shows that DHCP is enabled. It has successfully leased a unique IP address (192.168.1.12) from the DHCP server (192.168.1.1). It also has the correct Default Gateway (192.168.1.50) and DNS server information. This device is configured correctly and requires no changes.

Server 1 is using the static IP address 192.168.1.1. Based on the DHCP information from PC 2, Server 1 is also functioning as the network's DHCP and DNS server. A server providing these critical network services requires a static IP address. While it is in a conflict state with PC 1, its own configuration is correct for its role. The conflict must be resolved by reconfiguring PC 1, not Server 1.

The network diagram and other device configurations show the router's IP address is 192.168.1.50, which should be the default gateway for all devices. Server 2 is incorrectly configured with a default gateway of 192.168.1.5. This misconfiguration will prevent Server 2 from communicating with any devices outside of its local subnet. The gateway address must be corrected to match the router's IP address.

Chapter 10, Section 10.12 "Address Resolution Protocol (ARP)": Discusses how ARP is used to resolve IP addresses to MAC addresses and how duplicate IP addresses can cause "ARP poisoning" or resolution failures, leading to connectivity issues.

Chapter 20, Section 20.3 "The Domain Name System (DNS)": Explains the necessity of DNS servers for name resolution and why clients must be configured with the correct DNS server address.

Chapter 28, Section 28.5 "DHCP Address Assignment": Describes the process of dynamic host configuration, where a client broadcasts a request and a DHCP server assigns it a unique IP address from a predefined pool.

Chapter 5, Section 5.4 "The Internet Protocol (IP)": Details the structure of IP addresses and the importance of unique addressing within a subnet.

Chapter 5, Section 5.6.1 "Getting a Network Address": Covers the role of DHCP in automating the assignment of IP addresses, subnet masks, default gateways, and DNS servers to hosts. This section implicitly supports the remediation step of switching a client PC from a conflicting static IP to DHCP.
