This problem sounds like you have two hosts that have a duplicate IP address. The real trick will be finding the other host with the duplicate address. For troubleshooting purposes, boot the machine while it is disconnected from the Ethernet (if possible). See if you still get an IP stack disabled message. If not, then reconnect to the network and see if the problem reappears. If it does, then you likely have a duplicate IP address. If you have a small network, check each machine to see who has the duplicate address. If you have a large switched internetwork, you will likely need to check the ARP cache of the RSM/external router to see the IP/MAC pair for the duplicate address. Then you will need to go switch hopping in your switch CAM tables to find out which port that host is attached. The most common reason this occurs is when you have a DHCP environment and somebody out there insists on setting their own IP addr and they set it to an address within a valid scope.
