How do I access a Domain Computer via a Direct Connection

I have an older model CNC machine that requires a direct connection to a host PC. That PC is also part of a domain. To solve this, a second NIC was installed into the Domain PC and given a separate IP address with a different netwokr id (192.168.2 vs. 10.1.50). The CNC controller can ping the host PC, but I cannot get it to connect and extract the files needed. Since I can ping the host, my belief is that it has to be a permission problem. Complicating this is that there is no DNS server available to that CNC thus there is no way to resolve the server name. Recognizing that, the IP address was used instead, but still no connection. Any ideas? The OS on the CNC is Windows CE; the host is running W7 Pro.

All indications are that the Main Control Board on the CNC mill is bad; support has been called. Question closed.

In the Network and Sharing Center control panel under Advanced settings on the left, make sure File and Printer Sharing and Network Discovery are switched on for which ever profile (Home, Public or Work) the CNC subnet is in.

That has been done. Still cannot connect, however.

What about firewall settings? Turn it off completely and test. But you can't leave it completely off. We just need to see if it's stopping the connection.

Firewall was turned off; still no connection. Pings are intermittent as well. Sometimes there is 100% response; sometimes there is loss. The cable is only 35 feet long and is a crossover cable connecting the two computers. Pings are one way. The HOST Workstation will only see the CNC computer once in awhile. I attribute this to the fact that the HOST itself is part of a domain, is connected to a DOMAIN, while the direct connection is a secondary network although the main network for the CNC computer. There is no way to assign both ends to a separate workgroup.

What happens if you lose the crossover cable and connect the CNC and PC via a mini switch?

Sorry about the late response, I did not see this before. What you have suggested is how we originally set up the CNC mill. Late last year we started having network connectivity issues, which were resolved to a large degree but not eliminated. For the past 2 weeks, however, we have experienced 75% downtime hence the direct connection try. We are in contact with the Support team to see if perhaps our problem is hardware related on the mill.

That fits the symptoms. NIC's can and do go bad.

Issue was not a network problem but hardware related
