Deleting a IP address

[Chuckster]

I recently setup a server for a play around and gave it the IP address of x.x.x.3. The computer name was random, e.g. server28230984.

I rebuilt the server yesterday and this time gave it a proper name of "Test Server" and tried to give it the same IP: x.x.x.3

My problem is I'm not able to give it this IP since it's already being used. I've checked the DHCP but our scope starts from x.x.x.45 - x.x.x.253

How can I delete the x.x.x.3 so that I can re-issue it to the newly rebuilt server?

How do you mean its being used? Do you get an error message when you try and give it a static address?

I get an error message saying it's already in use and the LAN icon in the taskbar shows a big red X or question mark - can't remember which.

try pinging .3 from another location see if it replies

then arp -a to get the mac address of it if it is actually replying

Delete the old entry from the DNS server unless you scavenge the DNS.
