I ran across a problem today with a new server of mine. We have a SBS 2003 server that had a problem with the motherboard. Upon replacing the board, the integrated NICs obtained DHCP addresses. When I attempted to change to a static address, I recieved error: The IP address x.x.x.x you have entered for this network adapter is already assigned to another adapter. I researched and found MS Q269155 describing the exact problem I have, but when I follow the steps outlined, there are no additional adapters listed. As a temporary fix, I assigned a different address and reconfigured DHCP and DNS, but I would like to know how to go about fixing the problem. Any help is greatly appreciated.
