Windows release DHCP IP Address and get a new one

 Working remotely is quite a norm in today's pandemic world.

 IT / System Admin working remotely may find it difficult or a good opportunity to work at the comfort at their own homes.

Difficult in a way, when something goes wrong on a server or any device and you need a physical hand even just to force power off and turn it back on may seem an impossible task.

DHCP is an amazing technology that lets machines auto configured themselves with an IP Address without human intervention.

But not everything seems to work smoothly at times, and if you have multiple networks in a single manage switch.

Changing one network from another makes life easier using a manage switch.

However, the machine, server or computer may not change easily; you either need to reboot the machine or just simply release and renew the DHCP to set or get the desired IP Address from a new network profile.

In Windows DHCP network, ipconfig /release will release the IP and the machine will be automatically disconnected from the network; a horrible thing to do when working remotely, ultimately you won't be able to take hold of the device unless there is some human intervention onsite. A right thing to do is to release the IP Address and get another IP Address after releasing the current IP.

So, how to release DHCP IP and renew it automatically?

In Linux you can combine commands in single line, and it will execute in the order you define the commands on the line.

Yes, Windows is able to do this as well.  By using the command below this will release the DHCP IP and renew it automatically after releasing the IP.

Releasing and renewing DHCP IP Address must be done in an elevated mode or the admin command prompt, here's how to do it:

 ipconfig /release && ipconfig /renew

 

So, what it does it will release the IP and at the same time renew or get a new DHCP IP.

The remote user will be disconnected after releasing the IP Address; however, the machine will be back online once it renewed or get a new IP Address. Provided of course, that everything works smoothly.

One way to ensure that you will be able to get back to the device is to check whether the DHCP is up and running and has enough IP Address to lease to the client.

With that being said, it's better to try the command in your own local Windows machine and see if it works as expected. Again, there are thousands of reasons that renew DHCP may not succeed.

So, better tread carefully especially if you are working remotely.

 

Cheers. Till next time.

Notepad++ can process the contents of the file using regex. Example if the data has multiple rows or lines, and what is needed is to convert the whole lines of data into a single line.

WMIC is a command-line tool and that can generate information about computer model, its manufacturer, its username and other informations depending on the parameters provided.
