two machines have the same ip address

dear all ,

i have 2 machines A and B have the same ip in the inventory and both of them are active

When i do any task on the machine B , it shows that it is off ( also i cant ping it using the name "B" )

But when i do remote control on the machine B it remote control the machine A

Note that both of them have the 2 icons for remote control and standerd agent

Any help will be appreciated  ????
