I am sorry if this is a double post. I thought I posted this question yesterday, but cannot find it.

We are going to start the process of changing our network numbering scheme from 192.168.88.0/24 to 10.0.1.0/24. There are approximately 50 devices on our network. To avoid having to visit each workstation individually, I would like to change the network settings using TCL and twapi if possible.

Is it possible to query a remote workstation using twapi? All of the information I have found leads me to believe it is possible using the comm module. However, I have not found an example or found the right combination to make the two work together.

Is it possible to change network settings on a workstation using TCL, twapi and WMI? From what I have read about twapi, it is possible to query WMI, but I have not seen any mention of the possibility of changing settings.

If there is a better tool for this, I am open to suggestions. TCL is the language my predecessor was using and I am trying to keep things the same as they are since others outside of IT somewhat understand what is going on.

    If you are not yet using DHCP, then now might be a good time to start using that. If you are, just change the DHCP server settings. – Hennes Jan 28 '13 at 00:30

The better tool for this is DHCP.

Assuming you have a domain, you can set this with a GPO that you push out to all your clients. If not, you can use a tool like psexec, or WMI queries, to set the remote computers to pick up their addresses and network settings from a DHCP server. The CLI commands to tell your computers to pick up their IP address and DNS servers from DHCP would look something like:

netsh interface ip set address name="Local Area Connection" source=dhcp

netsh interface ip set dns name="Local Area Connection" source=dhcp

Come to think of it, you could even set those commands in a start up script or similar and automatically deploy it to all your computers with minimal effort.

Setting up a Windows DHCP server is pretty easy (almost self explanatory) and easy to find tutorials for online.

  • Not to mention, if you have 50 computers you should already have Active Directory, DNS and DHCP in the mix somewhere. – Michael Hampton Jan 28 '13 at 01:21
  • @MichaelHampton Right, but if everyone already did, guys like me wouldn't be able to charge a few grand for the 15 minutes of actual work it takes setting it up. =D – HopelessN00b Jan 28 '13 at 01:22
