Detected ARP cache poisoning attack

[ScottWStewart 2]

One computer on my network is being detected by other PCs as sending an  ARP cache poisoning attack. The computer that is being detected as sending an ARP attack has the latest ESET Endpoint Security and defs. One note, the user that uses this workstation complains about the PC being slow. How to I stop the computer doing the attacking to stop? Below is details and screenshot from ESET Remote Administrator. Thanks in advance

Duplicate IP addresses were detected in the network. Make sure that each computer has a unique IP address.

Do you have a server with two or more network adapters for redundancy in the network?
