A user turns on a new laptop and attempts to log in to specialized software, but receives a message stating that the address is already in use. The user logs on to the old desktop and receives the same message. A technician checks the account and sees a comment that the user requires a specifically allocated address before connecting to the software. Which of the following should the technician do to MOST likely resolve the issue?

Question

Accepted Answer

B. Set the laptop configuration to DHCP to prevent conflicts. Since the account notes require a specifically allocated (static) IP address for the software to function, the desktop must retain that static IP. The new laptop was likely manually configured with the same static IP, causing the 'address already in use' conflict on both devices. Setting the laptop to DHCP causes it to obtain a unique address from the DHCP server, eliminating the conflict while preserving the desktop's required static IP assignment.

Answer

A. Bridge the LAN connection between the laptop and the desktop. Bridging LAN connections between the laptop and desktop would not resolve an IP address conflict and would create an unnecessary and potentially disruptive network configuration.

Answer

C. Remove the static IP configuration from the desktop. Removing the static IP from the desktop would eliminate the specifically allocated address that the user's software requires, preventing the software from functioning on the correct device.

Answer

D. Replace the network card in the laptop, as it may be defective. A defective NIC would cause connectivity failure, not an 'address already in use' error, which is a Layer 3 IP conflict symptom.
