•Problem: DHCP server issuing IP address that causes duplicate IP on network.

Explanation: The DHCP server in question is not detecting an address and is provisioning a duplicate.

Remedy: This problem can be caused by a statically configured PC. Find the statically configured PC on the network and changes its IP address to a valid and unique IP address. Merging two unique networks into one can lead to this type of problem. The problem can also point to an issue with a DHCP server or an implementation bug.

Name Resolution

•Problem: No DNS server found on network to resolve names.

•Problem: DNS resolution failed.

Remedy: You can manually fix this problem in the DNS configuration section of network properties.

•Problem: Incorrect WINS server xxx.xxx.xxx.xxx configured on PC.
