User believe that another machine on our network attempt to use the ip reserved for his workstation. We knew the user's ip address and the mac address offending his nic. I checked the log on the switch and didn't find any duplicate IP error.

Can anyone help me with steps to get it fixed?

The IP address in a Duplicate IP address error message received on the interface is the same as the switch's own IP address. This condition may be caused by a network loop, a misconfiguration, or a malfunctioning switch. So, Ensure that there are no network loops, check the configuration on all, and make sure that all switches is correctly configured and functioning properly.
