Newbie DHCP Question 1

[Rene1024]

I have a small network where the ip addresses range from 192.168.1.1 to 192.168.1.254

I would like to change the range to 192.168.2.1 to 192.168.2.254

The netwrok is set up with a DHCP server, what would be the easiest way to do this without affecting the clients?

Thanks.

Rgds.

What is acting as your DHCP server? Is it Windows 2000 Server or a device like a Linksys router?

The process is different depending on what you have.

Thanks for the reply Steven,

My DHCP is a Windows 2000 server.

In this case, you would actually have to delete the scope and then create a new one with the IP range that you want. You will also have to change the IP address of the DHCP server to be on the same IP range as the clients.

Since you have a small network, I assume you can do this with minimal affect on the clients.

Sorry, my mistake. I was thinking of changing the Subnet Mask. You should be able modify the IP range in the scope but you will still need to change the IP address of the server to be local on the 192.168.2.0 subnet.

My current DHCP server Ip address is 192.168.1.2, I will change it to 192.168.2.2

I will create a new scope range from 192.168.2.1 to 192.168.2.254

After I make the change, do the clients just need reboot to get a new ip address with the new subnet?

Thanks again for your help.

You can reboot the clients or you can run ipconfig /release and then ipconfig /renew in a command prompt on the clients. Rebooting is probably the quickest way to do multiple clients.
