Answer:
A possible break along the network line from PC1 and PC2 cable. Or the the network configuration has been altered
Step-by-step explanation:
When a network cable transmitting signals from a system to a server experiences truncation along it path, the unit that is broken ceased to send packages across to the server.
When the technicians performed the swapping techniques between the two PCs and the outcome remained the same, it was a clear pointer to the fact that it wasn't an NIC issues.
On the other hand, run an ipconfig command on the command prompt to find out if packages received are not truncated. If it is. Then verify the new IP address and align it with PC1 and PC2.
