Trying to replace SBS 2003, can I keep IP address?

I have SBS 2003 running for AD, but I want to replace the box because it is 5 years old.  Only 5 users, but always in use.  My plan was to install a new copy of SBS 2003 on the new box, keeping the same domain and IP,  and then reenter in the groups, users and computers from scratch.  

In the installation, when it came time to assign the IP address to the new server, I unplugged the old server and plugged in the new.  I entered the old address  (10.0.10.100)  I got a message that "The specified IP address is already in use."  The two servers were never connected to the network at the same time.  What is causing the new server to view the IP address as already taken, and how can I fix it?

Thanks,

Joshua

Someone is answering the ARP request if it says that the address is already in use. To know who, run

arp -a

And then hopefully the MAC address will tell you who. Are you certain that that is the IP of the old servern?

I am sure.  arp -a returns other IP addresses on the network, but not 10.0.10.100

In windows go to network configuration and make sure the network adapters are set to dhcp.  Then rerun the installation wizard.  This should do the trick for you as I have run into that before.  Good luck, Rob.

Thanks to you both.
This is what worked -  I removed the server entry from the router network database  (Netgear FVL328) and then reran the installation wizard.  I kept the IP address as 10.0.10.100 and it worked.

I had previously tried deleting the address from the router database, but it only worked when I completely canceled and reran the installation wizard.
