| ## Overview - How CDS Looks Up Names This topic illustrates the relationship between a name and the physical resource that it describes, and explains how CDS handles requests to look up names. Understanding these concepts can help you to plan for the location of clearinghouses and directories in your cell namespace. It can also help you to isolate the source of a problem if you encounter lookup errors or failures. Note that the figures in this topic do not reflect the actual structure of a typical DCE cell namespace. For simplicity, the figures show fewer directories and directory levels. ##
