Remedy: Access PC network properties and correct the IP subnet mask.

•Problem: Router issued ICMP redirect. Hosts or devices using incorrect gateway/routers.

Explanation: NetTool has determined that the PC is not properly configured.

Remedy: Access PC network properties and correct the IP address. You should also make sure that the DHCP server is giving the correct addresses.

•Problem: Duplicate IP detected.

Explanation: NetTool has detected a duplicate IP address configured on a remote device. You should never have duplicate IPs running on the network. This problem prevents the PC from connecting to the network until it is resolved.

Remedy: Identify at least one of the devices and change its address to a valid one that is not being used.

Host Configuration

•Problem: BootP/DHCP server not responding.

Explanation: The PC is dynamically configured to find DHCP servers and none are found.

Remedy: Check the router and the DHCP server itself to make sure that they are running. Either could be misconfigured. Check connectivity to the DHCP server.
