Hi @Lui13 ,

 

You can try to traceroute or ping the device with IP address from fortigate CLI.

 

On your windows machine, you can check if there is another device with same IP address and find out which device that is using MAC address.

 

You will need to check ARP table on Windows PC using "arp -a" command and find out which device is having the same IP address.
