What I need to do rectify this issue?

I received this message from so many IPes in my network.

I mean DHCP pool in my fortgate Firewall

Dear All Every day I received one message from ESET End Point Security regarding, A device on the network is sending malicious traffic. This can be an attempt to attack your computer. The threat was block. After received this message my internet connection suddenly disconnect. After restart my Firewall it will work. As per my knowledge this message coming because of the duplicate IP address in my network. How I fix this issue. I have DHCP pool in my firewall. I think that pool is not working properly. some time this message coming with default gateway IP. If I disable and enable DHCP pool from my firewall it can be fix this issue? Thanks
