DNS Server Randomly Changes

Most of the time when a user logs on, he or she receives the proper DNS server IP addresses. They receive addresses via DHCP. However, after a few minutes, their DNS server IP address changes to 192.168.1.1. A quick release/renew fixes the problem temporarily but it keeps happening.

Has anyone experienced a similar problem? If so how did you resolve it?
