    Network Picking up another network ip address

    I have two networks here, and they both have there on ip range.

    Both networks are picking up the other networks IP addresses.

    Both of these network are link together but can see each other.

    It has been fine for 4 years now all of sudden this happens.

    Does anybody know what could be causing this

    Thanks
    Amallia

    Has someone plugged a cable in where they shouldn't in a cabinet? Do you have comms cabinets accessible in public areas where people can fiddle?

    Interesting.... the cable seems very likely. Are these on VLAN's or something maybe someone has changed the switch configuration.............

    Have you checked the DHCP server see what's happening.

    or it could be a statically assigned IP somewhere, I'd Wireshark it and try to se what is being broadcast could be a spyware/malware issue.
