Configuring Network Connections in Windows 2008R2

A project I have been working on required us to add another NIC to all of our servers.  We didn't want production traffic accidentally being routed over that subnet.  Below are the steps we took on the servers to prevent it.

• Hit the Windows+R keys simultaneously
• Type control netconnections and then click OK
  
• Right Click on the connection you don't want traffic to go over and select Properties.
• Uncheck all item except for Internet Protocol Version 4 (TCP/IPv4).

• Right click on IPv4 and select Properties and set a static IP address for the new subnet.  In the picture below the IP is just an example (shouldn't use .1 as that is normally for your gateway)
• Click on Advanced and select the DNS tab.  Uncheck Register this connection's addresses in DNS.  Click on OK and OK to save the changes
  
• Right click on the connection we just changed and select Rename
• Pick a descriptive name for this connection
• While in the Network Connections Window hit the Alt key.  You should see a hidden menu pop up at the top.  Click on Advanced à Advanced Settings
  
• Change the connection you renamed to be below the other connections.
  
• Click on OK to save the changes.
• Next we want to make sure another default gateway wasn't created when the NIC was added.  Open up a command prompt and type in route print
• If there are more than one default gateways (0.0.0.0) and one of them is the new subnet you will need to remove it.
• route DELETE 0.0.0.0 255.255.255.0 10.10.10.1 servername
