- Define a domain hierarchy
- Name domains
About This Lab
In this lab, you will analyze portions of the existing environment at a medium-sized company to define domains, define a forest root domain, define a domain hierarchy, name domains, and plan DNS server deployment.
Before You Begin
Before you begin this lab, you must be able to
- Analyze an organization's environment to define its domains
- Analyze an organization's environment to define its forest root domain
- Analyze an organization's environment to define its domain hierarchy
- Analyze an organization's environment to name its domains
Exercise: Creating a Domain Plan
In this exercise, you will analyze the existing environment at a medium-sized company to create a domain plan, which includes a network architecture diagram with the domains and forest root domain indicated and a domain hierarchy diagram with named domains. Review the scenario; then follow the instructions to create the domain plan.
Your design team is planning the Active Directory infrastructure for Parnell Aerospace, a developer and manufacturer of commercial and military aircraft. Parnell's headquarters is in Phoenix, Arizona. Last year Parnell Aerospace acquired Lakes & Sons, a developer and manufacturer of small private aircraft. Parnell Aerospace has approximately 63,000 employees worldwide. Six regional offices, in New York, Tokyo, Berlin, London, Paris, and Rio de Janeiro, link to headquarters; each regional office has 5 to 10 sales offices. Lakes & Sons has 5,000 employees in Seattle and 3,000 employees in Minneapolis. Each location has two sales offices.
While reading through the business and technical environment analysis documents, you note the following requirements:
- Because Parnell Aerospace is a defense contractor for the governments of many countries, the company must meet special legal requirements for storing product development files at headquarters.
- The Tokyo location requires special password and account lockout settings.
- German laws require that the Berlin location be administered only by an office in Germany or by company headquarters in Phoenix.
- French law requires that the Paris location have more relaxed Kerberos settings than any of the other locations.
- Lakes & Sons will function independently and have its own Web presence; however, the forest model compiled by the design team requires only one forest.
- At the Phoenix headquarters, two separate departments handle IT management. One department handles IT management for the Phoenix office only, and the other handles IT management for the entire organization.
- At Lakes & Sons, two separate departments handle IT management. One department handles IT management for the Minneapolis office only, and the other group handles IT management for the entire Lakes & Sons organization.

- Users at all locations must often access engineering resources at the Phoenix location.
- The Engineering department in Phoenix currently has its own Windows NT 4 domain. They would like to keep their domain, but there are no particular security, administrative, or replication issues that warrant using a separate domain.
- Parnell Aerospace currently has a Web presence and uses the DNS name p-100times.com.
- Lakes & Sons currently has a Web presence and uses the DNS name l-100times.com.

Answer the following questions to create a domain plan.
- On the network architecture diagram, use a triangle to indicate the location of the domain(s) you would define for Parnell Aerospace. Explain your reasoning for defining the domain(s).
- On the network architecture diagram, draw a square around the domain you're defining as the forest root domain. Explain your reasoning for defining the forest root domain.
- Complete a domain hierarchy diagram for Parnell Aerospace. Name the domains in the domain hierarchy.
