General Information
Introduction
You have been hired by Fourth Coffee to design their implementation of Microsoft® Exchange 2000 Server You have been asked to provide a design that includes support for their wide area network (WAN) links, messaging infrastructure, directory design, and reliability needs
Background
Fourth Coffee is a privately held company that has been in business for 50 years Fourth Coffee’s business is the importing and processing of specialty coffee beans
Company Profile
The company employs 3,000 employees The company has five offices, which are all located within the United States The company’s headquarters is located
in Portland, Oregon The following table lists the locations of all five offices and the number of employees retained by each office
Because the nature of Fourth Coffee’s business requires frequent international travel and frequent customer meetings, all employees in the company except those in administrative support positions have portable computers
Factors That Influence Business Strategies
The owners of Fourth Coffee believe that their company's business is coffee
beans—and not technology Therefore, the owners want to ensure that any
expenditure made for additional technology is absolutely necessary This does not mean that additional services and equipment cannot be purchased, only that each purchase must be fully justified
Trang 4IT Environment
Overview
Fourth Coffee currently uses an outdated version of Lotus cc:Mail Lotus cc:Mail is only used for basic mailbox configurations
All network servers are running Microsoft Windows® 2000 Server, and the Microsoft Active Directory™ directory service is running in native mode All client computers on the network are running Microsoft Windows 2000 Professional The company wants to use Microsoft Outlook® 2000 as the standard messaging application
Because the company’s IT group is small, Exchange 2000 Server management should be simplified wherever possible For example, properties should be configured on the entire mailbox store rather than on individual user mailboxes
Administrative Model
The IT group is centralized in the Portland, Oregon office This group is responsible for all network administration, including routing infrastructure, messaging, and network permissions This group is also responsible for Exchange 2000 Server permissions and for maintaining Active Directory
Messaging Environment
Fourth Coffee wants to implement a 40 megabyte (MB) storage limit for each employee Company executives will not have a storage limit
Fourth Coffee wants to have the ability to control message flow between all office locations
The server hardware that is available for the deployment of Exchange 2000 Server is able to support up to 800 mailboxes on each physical server
A digital linear tape (DLT) tape library is attached to one server in each office The DLT tape library performs backups on all servers in each office and is able
to back up approximately 7 gigabytes (GB) per hour

Network Infrastructure
While out of the office, employees connect to the company network by using dial-up connections to a server running both Windows 2000 Server and Routing and Remote Access Service (RRAS)
Each office has a 10 megabit per second (Mbps) Ethernet network for all servers and all client computers
All four of the company's other offices connect to the Portland, Oregon office
by using 768 kilobit per second (Kbps) Frame Relay Circuits
All employees access the Internet by using a Microsoft ISA Server that is located in the Portland, Oregon office
The IT group has convinced the owners that Outlook 2000 client performance will be decreased if the users in each office must connect to mailbox servers in Portland
Trang 6Exchange 2000 Server Requirements and Goals
Security Requirements
Fourth Coffee wants to ensure that its servers running Exchange 2000 are not used to relay unsolicited commercial e-mail (UCE) They also want to protect employees from receiving UCE messages and e-mail from non-existent Internet domains
The Portland, Oregon office has a perimeter network that contains a server running Internet Information Services that provides Web content for business partners and customers The perimeter network is configured to allow only Hypertext Transfer Protocol (HTTP) port 80 and Secure Sockets Layer (SSL) port 443 traffic into and out of the perimeter network If it is necessary to do so
in order to meet business requirements, additional ports can be opened
Availability Requirements
Fourth Coffee wants to ensure that its servers are configured for optimal performance and availability They do not believe that either clustering or load balancing is a requirement for their business
Design Goals
To reduce the cost of remote connections for its employees, Fourth Coffee wants to explore the return on investment of using virtual private network (VPN) access instead of asynchronous RRAS connections
The Exchange 2000 Server design should use the available server hardware as efficiently as possible Therefore, when possible, servers should be configured for multiple roles For example, one server could perform both as a mailbox and
as a public folder server
