For a heavy scientific calculation I am running I need to distribute the work over the network to many clients. The software we use acts as a server and is able to connect to clients to give them small portions of work for processing.

But we have a 50/50 mix of Mac and PC machines here, which is really a problem. Nobody was able to get them talk to each other. Nobody in our living community is experienced in networking to make this work, and I wasn't very lucky finding good resources which wouldn't be as complex as studying the whole topic at university.

What we need is simply that the Mac (Snow Leopard) appears as a node in the network list in Windows 7 Professional 64bit, and vice versa.

All machines are connected to a ZyXel router which does not provide Static DHCP. The menu of the router does not offer to assign fixed IP addresses to the devices connected with that router, and the IP addresses seem to change often.

I've used a little Mac app called LanScan which lists all devices connected to the router, giving their IP and MAC address. But the Mac itself doesn't show them, so doesn't Win7Pro.

Can someone point me to a newbie-proof guide or tutorial which explains step-by-step how to establish a functional network between Mac and PC using a router inbetween?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.If this question can be reworded to fit the rules in the help center, please edit the question.

  • If all nodes have TCP/IP enabled
  • If all nodes will get fixed (user-defined) IP-settings for their LAN-interface and they will be placed inside one net
  • If ICMP echo-request/echo-reply will not be blocked by clients firewall

you can test net-health using ping ping ip-of-any-lan-host

After it running TCP/UDP server and connecting to it from clients (you know IP of your server!) will be trivial task - "just run it!"
