Dual NIC Issue/Help

So lets say I have a PC with at least 2 Ethernet ports. One is assigned an IP from DHCP, and one is set manually. They are different subnets, so for example: NIC 1: IP: 10.36.8. Subnet: 255.255.254.0 Gateway: 10.36.8.1 etc... NIC 2: IP: 192.168.0.1 Subnet: 255.255.255.0 The problem I have is this. When both adapters are enabled the internet doesn't work. It appears the computer is trying to use NIC 2, if I set a gateway address for NIC 2 would that fix this issue? I see this on multiple PC's and it's pissing me off! ------------------------------------------------------------------------ "If you don't like donut, then leave it alone.

Presumably only one of the NICs is connected to a network which has Internet access? The GUI way is to go into TCP/IPv4 Properties, Advanced, and set a default gateway with a metric lower than any other default gateways (Windows will prefer the default gateway with the lowest metric). If you're still a bit stuck, do a "route print" and show us/me - via Hangouts if you want it less public. If your machine is configured to use a DNS server on one of the local LANs, you'll need to make sure it's reachable. [...Insert Brain Here...]

I'd say get rid of the DFGW completely on the second NIC. Even with metrics, it doesn't really make much sense to have two gateways defined IMHO - should just add static routes if required. Dan Herman
