Hey, I've been troubleshooting network issues on servers with 2 NICs and laptops with wired and wireless cards. How can I force the PING and TELNET to be sent from a specific adapter? I know it's a trouble with windows. Turning off one of the adapters is not an option, I am always connected through one of the adapters. There must be some command line option to prefer one adapter over the other. Thanks

You can set a static route: For more info, check out Microsoft's documentation on | |||

The adapter chosen is based on the routing tables. You can examine the routing tables by running 'route print' or 'netstat -r'. Each entry will have a metric which dictates the weighting of the route - lower numbers are preferred. You can manipulate the routing table with the 'route' command. route /? for details. | |||

Probably easier is to use the -s switch, which lets you specific the source IP address. Do ping /? for more information. Another thing you can do is change the binding order, which meets your "option to prefer one adapter over the other". Although it varies from Windows OS to OS, it is in a similar location as this example: For Windows 7 you right click on Network, and click properties. Then you click on ""Change adapter settings". Then click on the menu Advanced>Advanced Settings and move the connection you want to have priority to the top. | ||||
