I have an MRI equipment connected to a PC. The MRI sends the files to the PC to be burned to a CD.
The doctors want to have access to the internet and be able to maintain the connection to the MRI equipment as well.
The Clinic's network is in the 192.168.1.0 segment and the PC is connected to thenetwork via wireless PCI Card for Internet Access. The Wired NIC from the PC is the interface to the MRI equipment on a peer to peer connection to the MRI server.
The problem is that if I use the internet then they cannot connect to the MRI equipment. I would like to know how to maintain the connection to both networks.
IF not possible, then I need a batch file that can allow me to disable the wireless NIC and enable the LAN Nic and vice-versa. Can someone post the script to test it??
Thank you

Try checking the properties of the NIC card that is connected to the MRI equipment. If that NIC has a default gateway setting, REMOVE it.

If that doesn't help, post again with specific IP addressing info for both NICs - that would help a lot in troubleshooting the problem.

Hope this helps!

Is the MRI equipment connected via ethernet? if so does the MRI equipment have it's own IP. Is it a direct Xover NIC to NIC?

IF you multihome the box, both NICs ought to have static IPs on different subnets.

That is correct.
I have the wireless NIC with 192.168.1.201/255.255.255.0 with 192.168.1.254 as gateway.
The NIC connected to the MRI has 129.10.171.10 /255.255.255.0 - no gateway

the MRI machine IS in the same subnet as the wired nic? Not to insult you, but sometimes a subnet mask is off. Layer 1, then layer 2, etc...

by dumphrey

is how the MRI program is being called, by ip or by dns...I would add an entry to the hosts file for the MRI machine.

direct Xover cable to the MRI unit with the MRI interface NIC with a IP address? whats the IP of the MRI NIC? How does the application that is being used create a connection? its possible the application is web enabled therefore sends out a web request which would go over the NIC that has the gateway configured. I do not think a script would help. If the MRI is a local address then you might consider a proxy server for internet access on the box. Then local address web requests would bypass the proxy and go directly to the local host.

Try entring the Default Gateway you use as the proxy IP in the Internet Explorer.

Also you can try to fix the routes using:

Route ADD [Destination] MASK [MASK] [GATEWAY] METRIC [METRIC] IF [INTERFACE NUMBER]
