It really does depend on how the routers and systems on the network are configured.

At our office, our machines will not connect to the local domain due to the collision in MAC addresses. You'll get a notification message (in Windows) saying there is already a system with the Id on the network.

Sometimes you get into "races" where each computer attempts to register itself with the router, and any traffic coming to the machine can get lost since packet A will go to your machine, the other machine will register, so packet B will go there. Things can start bouncing back and forth.

You can start seeing unreachable host errors due to the collisions as well.

The results really do vary depending on when the duplicate machine is coming online and how the current infrastructure is setup to handle such items.

Your network admin will have more detailed answers on this.

Hi@AAA1992
Yes it is possible, if another computer uses tool like MAC changer in linux os to copy the another computers MAC address. Else MAC is a unique address for each device for communication on network.

You can have 2 pc with the same MAC, if the switch is not managed without software or the switch is managed but without port security then will not trigger security problem. Ethernet switch keeps a table of which MAC addresses are attached to which ports. two hosts (both same MAC address), then the switch will update it's MAC table every time it receives a frame from either host, the problem is a constantly changing switching table.
