Existing Environment
Each North America office is connected to a frame relay network by means of a 56 Kbps circuit. A permanent virtual circuit (PVC) exists from each North America district office
to the Portland Office. A 128 Kbps leased line connects the Portland Office to each regional headquarters. Each regional headquarters outside the United States connects to
its district offices by means of a 256 kbps leased line. The Portland office is connected to the Internet by means of a T1 line to an Internet Service Provider (ISP)
Routers and DSU/CSU are installed at all company locations. Routers contain hardware from a variety of manufacturers. All routers are BOOTP enabled.
Hanson Brothers has the following client computers evenly distributed throughout its organization:
* 1000 Pentium III computers that are running Windows NT 4.0
* 1500 Pentium I computers that are running Microsoft Windows 95
One primary domain controller, one backup domain controller, and five file and print servers are located in the Portland office. The Portland office also contains two proxy servers, configured as an array, that provide Web cache services and Internet access control. A few locations throughout the company contain servers that provide Windows NT4 DHCP services.
A single Windows NT domain exists for email authentication and for Internet access control on the proxy array. Client computers throughout the company log on to the domain only when they need to access these services.
Interviews: CEO:
In the past four years, we have undergone rapid growth. For example, we have opened many new offices in through locations, and the number of employees in your company
has tripled
CIO:
Our Corporate philosophy favors the centralized control of most business process. However, this philosophy is being shared by the company’s rapid growth and expansion. We want to decentralize the administration of the network by creating three categories of administrators teams Enterprise, Regional and Site.
The Portland office will contain an enterprise, a regional and site administrator team. Each regional headquarters office will contain a regional and a site administrator team. Each district office will contain only site administrator.
Although Hanson Brothers has limited Internet presence, Internet resources play an important
Role for the research company performs to its customers. Although our foreign offices have been reporting slow Internet performance, employees at the Portland Office report than Internet performance is more than acceptable.
In our company, we want to deploy several important web based applications. This deployment requires the creation of internal Web sites. All intranet Web servers will be located in Portland Office. One of these Web based applications concern all human resources files in a single location that users can view through their browser. These files are created and updated regularly by the human resources directors in each regional headquarters. These directors will need local access to their files, and the Internet server

will need local access to the human resources files created and updated in these locations.
Because the links to the regional headquarters outside the United States are very
expensive, the bandwidth must be used wisely. We want to minimize increase in costs for
WAN connectivity wherever possible.
We want to immediately upgrade all Windows NT4 client computers to Windows 2000 professional. We will not upgrade the existing Microsoft Windows 95 client computers. We will replace them over the next two years with new computers running Windows
2000 Professional
Security Manager:
Currently the Portland Office has an Internet connection that is secured with a firewall. The firewall is running network address translation (NAT). My security team is located
in the Portland office, and all extranet connections will be located in this office.
Active Directory Design Team Leader:
For our Active Directory design, we will use a model containing a single forest with a single tree that has multiple domains. Each domain will contain one regional headquarters and all of its district offices. The domain will use the following names:
* Asia
* Europe
* LAmerica
* NAmerica
* SPacific
A new parent domain named Corp will also be created to hold the enterprise administrator team accounts and the forest level accounts
We will use Active Directory namespaces that are contiguous with the existing registered domain name. All DHCP servers will reside on member servers, and the DNS zones
should be configured to run in a multi-master mode. The security team will configure the firewall so that no Active directory DNS server will have access to the internet. Each regional headquarters will contain a domain controller that is configured as a replication bridgehead server. Each regional administrator team will manage all DHCP servers in its region regardless of the servers physical location.
Network Administrator
Currently, all routers are configured by using static routes. However, as our company expands, static routing is becoming increasingly inefficient.
We have a lot of downtime with the old system, and redundancy is extremely important
to us.
We have several applications that all offices within a region use. We want to give the regional administrators the ability to manage these installation packages. An administrator also needs the ability to publish these applications so that they can be installed the first time they are used. Although some of the installation packages are large, we want the quickest installation possible.
Almost all users will require access to the Internet so that they can browse the web. However, only a few users will need access to FTP. The users in a region visit many of the same company and government web sites as other users in their region.
Hanson Brothers has a registered DNS namespace of hansbrothers.com. This namespace
is held by a Unix server in the Corporate office that is running BIND version 4.8.3. This server will not be upgraded.
