1. The HDLP agent does not interfere with the working of the DNS client. The DLP agent uses the DNS to query whether the EPO server is available or not.
2. The DLP agent obtains the IP address and server name of ePO from the registry. These values are placed in the registry by the McAfee Agent.
If there is an incorrect configuration of IP address and the EPO server then McAfee Agent will also not communicate with the EPO server.
