I'm having troubles connecting two machines on my network, and need some help from the Experts!
My local machine is a new Windows 10 box (but I had exactly the same issue when it was a Win7 box). The machine I'm trying to connect to is a Server 2008R2 box.
I have a Comcast Business router, and I've connected that to a Cisco RSV4000 router/firewall ONLY. I have several machines connected to that router, and I also have a Cisco /Linksys E4200 wireless router connected to one of those ports. The RSV4000 has DHCP enabled, and the E4200 has DCHP disabled.
From my local machine, I can run arp -a, and I see the address of the 2008 box, and I can ping it. The machine does not show up in my "Network" view. I see several other machines, and I can see the E4200, and I can see machines connected to the E4200. I can also see several printers connected to the RVS4000 Router - but I can't see the 2008 box.
From the 2008 box, I can run arp -a and I see the address of my Win10 box, but it does not respond to pings.
From EITHER box, I cannot see the other machine.
How can I get these machines to talk?
Note the 2008 box is being used for File Services, HyperV, RDS (and license server) and nothing else.
