    Dear friends,

    I've been trying to set up 2 different networks, actually to connect my mac pro with to two PCs. Well, I can't get my Mac to have access to the PC that is plugged into 2nd Ethernet port. However, if I unplug one of the cords, no matter what port it is 1 or 2, it works and sees connected PC.

    My IP addresses are set manually to 192.168.7.1 and 192.168.7.2. NetBIOS names are also different MACPRO and MACPRO2. Subnet mask is 255.255.255.0. Rest is not changed from defaults. And only 1 Ethernet interface sees the PCs.

    Could anyone suggest me something? Cos I really wanna have my Mac to be connected to these PCs.

    Thanks in advance.

    Most computers have problems if you have 2 different Ethernet ports on the same subnet number. One of the two will be the default port for items on that subnet.

    Easiest thing to do is to use a switch to connect all 3 computers.

    If you don't want to do that, then give one PC and the one Mac port a 192.168.0.x. addressing scheme, and the other a 192.168.1.x scheme (both 255.255.255.0) and be done with it.
