DHCP reservation

Windows 2000 advanced server running active directory, DNS and DHCP.

I currently use dhcp lease and want to change to reservation. I exclude the range of ip addresses and then add the reservation. But my quesiton is, how do I get it to release the current ip address? I am going to do this to about 250 computers.

I did a test reservation and it still shows up in leasing as an "inactive reservaton ". Is this correct?

 

start~run~ipconfig /renew from the client PC.

 

Is there a way to realease all dhcp from the server? I have 250 clients to do this on.

Should Dhcp lease say "inactive reservation "?

 

No way that I know of to do it en-mass from the server. There may be a tool but I don't know of any.

If you have a way to mass reboot the PCs, they should try and fail to regain their same IP address when they come back up and take a new one from your modified scheme.

Sorry but no clue about the "inactive reservation" part of your question.

 

Log on script?
Matt, where are you script writing guru....

 

Why does the reservation show up as "Inactive reservation "?

 

DHCP

Choose networking, then DHCP..Then drill down to whatever you want to look at. It's a very interesting site!
