A. Duplicate IP addresses have been assigned

B. IPX has been installed over IP

C. No WINS server has been defined on the network

D. The subnet mask is misconfigured

E. The cable might be loose

Explanation: Duplicate IP addresses are a common cause of communication problems, as is a misconfigured subnet mask. These problems, along with others, are why DHCP (Dynamic Host Configuration Protocol) is as popular as it is today.

A WINS server is not necessary for hosts to communicate, either with each other or with other hosts.

IPX and cabling are not IP addressing issues.
