    192.168.1.69 is machine B, but I do not know why 192.168.1.69 appears on machine A

    Both machines are posted above. Albert is B, Dad is A

    I did try swapping the cables between machines and the problem remains on B only. Here are both machines again, but this time B is shutdown while A runs the arp command, and vice versa.

    I wonder if 224.0.0.22 on B is the problem. No idea what that is.

    Each machine sees the other in its ARP table.
    The ARP table identifies/locates the other devices on your network.

    192.168.1.64 will have an entry for 192.168.1.69
    192.168.1.69 will have an entry for 192.168.1.64
    192.168.1.254 must be your router.

    As AddRAM asked, what is 192.168.1.65?

    But it`s pulling an ip address, why ?

    Can you do an ipconfig /all just on pc B or A whichever is showing .65

    As long as it only has 1 cable to it that should not be an issue. Every machine I build I throw a netgear card in , the drivers are in Windows and you know those Dells.

    Does disabling the unused NIC make a difference?

    I'll try that after I first load all the motherboard drivers. I should mention that I just built this machine B, and after the clean install device manager looked perfect so I did not load the motherboard drivers, other than to try a couple different levels of the realtek lan driver. I'll load all of the mobo drivers now and post back.

    That invalid 192.168.1.64 is still there even after rebooting twice, with only machine B turned on. So is that 224.0.0.22 under the wierd "Interface 0.0.0.0.----0xffffff" section for B

    I think you meant 192.168.1.65 is still there (192.168.1.64 is Dad)

    Are there any differences (success rate or times) when you "ping" one machine from the other?

    From 192.168.1.64 (using the "Command Prompt")
    ping 192.168.1.69
    and then the other way around.

    That is some sort of control/info channel.
    That is listed in my earlier picture also.
