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?
