When the domain name of an agent is changed, the new name isn't reflected in the Unified Management Console.
This issue affects Data Center Security 6.7 and earlier.
This has been fixed in Data Center Security 6.7 MP1 and later. When the value of domain name changes, the agent re-registers with the Management Server so that the value of modified domain name of an agent appears in the General tab of Assets > All Servers page in the Unified Management Console.
