Changing IP address in command line under NT?

[ugh]

HI all,

Anyone knows how to change the IP address for an NT machine using the command line? The ipconfig util only displays. What about changing the IP?

Thankss.

ha!

The IP is stored in the registry, I should imagine you could find a cmd line registry editing tool.

I am fairly sure Windows don't come with a tool for doing this.

ipconfig can release or renew your display, but no tcp/ip setting can be done from standard winnt command in command prompt.

if you use dhcp and your provider give you a new ip everytime you reboot, you could do ipconfig /release then ipconfig/renew

you cannot specify the IP that you get from dos command prompts from what I know. When I log in to my server from my dos station, it uses the DHCP. Why would you want to specify IP's from dos anyways???

W2K has reg.exe.
Or you can use regedit /s <filename>.reg to import regfiles from the commandline.

Ipnumber is located in keys:

HKLM\System\Currentcontrolset\Services\TCPIP\Parameters\Interfaces\{etc etc}\ IPAddress
And
HKLM\System\Currentcontrolset\Services\{etc etc}\Parameters\TCPIP\ IPAddress

{etc etc} is some generated name for your nic by Windows.

I don't know which one you have to change.
But you could use a tool like sed to manipulate a .reg file and merge it with regedit from within a batchfile.

Ofcourse all this will get you nowhere without you reapplying the configuration to the nic.
Maybe restarting of some network service will do the trick.

NiPeng: Ahh.. Thanks for the link to the registry entry. I think I know how to take it from here

With Win2K and XP you can use the command netsh.exe and then go to interface ip and make adjustments there. You may be able to copy netshell.dll and netsh.exe to an NT 4 system and try it there....

I wrote a batch file to easily switch ip settings between my home and work settings for my laptop using netsh.

here is the batch file - the remarks give the basic instructions on setting up the 2 text files you will need with your settings. A sample of my ipwork.cfg and iphome.cfg settings file is below that....

Let me know if you need any more details.

Completely forgot about netshell in W2K

*Nipeng makes a mental note

Hmmm... command line utilities in NT.... Makes my signature quote look more true every day..

At least I learned something in this thread too..good stuff... I also discovered you can do a &quot;netsh dump > dump.txt&quot; and see all the current settings for you network devices are... kind of gives you examples to come up with your own batch file.

Yup, netshell, iPconfig, RDP, windows scripting host, mounting volumes in directories....
