Using 2 Network Adapters with Windows 7
Posted on 2009-12-27
I have two local LAN networks with some XP, one Vista, a few W2000 systems and now a new Windows 7 system.
One network is for internet only and is connected with a router to a DSL modem. The router's IP is 192.168.0.1. The local IP addresses will be received from that router using DHCP. The only service used for those network adapters is TCP-IPv4.
The second network is for local data exchange only. It is workgroup based and the leading XP system has IP address 192.168.1.1. All computers have a second networkcard which is connected to a local switch.
Both networks were working.
Now the problem: For Windows 7 I used an Asus board with 2 Gigabit Network Adapters and achieved to configure those adapters to work like those of the other systems. I already achieved to copy most of the files from my main XP system using the second connection. But for unknown reasons the connection doesn't work anymore since a week or so. The issue is that the local net became a 'public network' and whatever I did since I recognized that my local net wasn't available in the explorere, I didn't achieve to both add an IP address like 192.168.1.9 and make the network a 'workstation-based' non-public network. The wizard always 'solved' my problem by activating DHCP and removing my IP address. However, the first network already is DHCP-driven and I don't want (and need) to mix thoses servcies. If I insist on setting a fixed IP address The network connection became a public network and isn't be available for local connection.
