I've done all of the things that I could find online (I'm not a network guy, but pretty tech savvy). Both firewalls are off. Connected to the same unmanaged switch. PC can see other Non-Mac network devices (Roku, my DiskStation SAN, etc.). Mac can see other Macs on the network that are set up for sharing and the SAN. On the Mac: Set a static IP. File Sharing turned on. WINS set to WORKGROUP On the PC: Set a (different) static IP. Sharing and Network Discovery turned on. Tried both private and public versions, currently both on. I've tried connecting over afp://static.ip both ways and can't connect. I ran nmap on the Mac and it could see the PC's static IP and shows several open TCP ports. The job: remote desktop into these bad boys and see if you get them talking to each other.

We have multiple black box applications that consume incoming UDP packets via a NIC and in response, publish outgoing TCP packets via the same (or a different NIC). These applications run on Windows and Linux servers, and they engage in tcp offloading to the NIC (kernel bypass). We're looking to build a tool/process that can help us accurately measure the wire-to-wire latency of these applications.
