Change default gateway with a script

Hi everyone,

I have a Windows 2003 network with 75 XP clients. I want to write a batch file script that I will run as a domain admin remotely against all client PCs to simply change the default gateway address for the "Local Area Connection" only.

I've been trying to write a script using netsh, but the syntax keeps causing me problems.

For example, I would like to change the default gateway from 192.168.1.1 to 192.168.1.5 on the Local Area Connection on all clients. All clients use static addressing.

Thanks for any help you can provide.

What errors are you seeing running netsh?

The correct command should be netsh interface ip set address gateway 192.168.1.5

Try this one first:

netsh interface ip set address name="Local Area Connection" gateway=192.168.1.5 gwmetric=0

If not working then try this:

netsh interface ip delete address "local area connection" gateway=all
netsh interface ip add address "local area connection" gateway=192.168.1.5 gwmetric=0

In the above commands, where is the remote system name/IP specified?

The commands should be run on the systems, not remotely. To launch it on the remote systems you have to use a workaround. For example, you could download and use PsExec utility: http://technet.microsoft.com/en-us/sysinternals/bb897553.aspx

Read carefully the usage / parameters. You might enter the computer name directly (like below) or use a file containing the list of the comouters.

psexec \\<computer> cmd /C "netsh interface ip set address name="Local Area Connection" gateway=192.168.1.5 gwmetric=0"
