You are a consultant and have been brought in to assist the Southwestern
Hospital Group (SHG) with its acquisition of the Western Arizona Thoracic Care
Hospital (WATCH). WATCH is a small 300-bed facility with approximately 1,500
full-time employees. The reasoning for the acquisition of this independent
hospital by the for-profit SHG group was to modernize and streamline WATCH. By
purchasing WATCH, SHGs cash flow could be applied to modernize and streamline
the WATCH facility and it could generate some profit for the SHG chain.
WATCH is set up with a Windows NT domain with a primary domain controller
(PDC) and a secondary domain controller (two of each controller). It has two
Linux boxes performing print server and Domain Name System (DNS) services. There
are a couple of Apache Web servers performing intranet and Internet functions.
The WATCH Internet site primarily is a static Web site with contact and facility
information aimed at promoting WATCH services to the community. The internal
intranet is used mainly for hospital policies and procedures. Also, the
employees can update employee information on WATCHs Web site.
Currently, several domains exist at WATCH. The administrative domain includes
the domain controllers, the Linux DNS servers, the Apache Web servers and 10
host computers. The bookkeeping domain includes accounts payable and employee
payroll and benefits processing. This domain has 50 client machines using an
Oracle database. The billing domain manages patient data, accounts receivable,
the Linux print servers, and 60 client computers. The patient records domain is
in an in-house hospital data system that uses SQL Server 7.0 Service Pack 3
(SP3). Users feel that this system is nearing the end of its functional life.
The proprietary system data is housed on an AS400 and is approximately 7
terabytes in size. In the nursing domain, there are three hosts in each of the
10 nurses stations and an additional 12 workstations deployed at various WATCH
locations for a total of 42 hosts. Backup duties are currently handled by
Automated Tape Library DLT Drives storage backup, which can back up
approximately 10 terabytes of data.
SHG wants to merge WATCH into its network infrastructure and centralize the
administrative domain into its central administrative site in San Diego. SHGs
network is a Windows 2000/2003 network with Active Directory. The patient
records application will eventually be merged into SHGs DB3 database hosted on
mainframes in the San Diego administrative site. SHG wants to eliminate paper
patient records as soon as possible and get WATCH to use its wireless patient
records and tracking application, which uses Palm handheld devices.
You will lead a team of eight administrators and network engineers consisting
of three WATCH administrators and five other contractor network engineers who
specialize in network migration and setup.
You have been asked to design and deliver a Microsoft PowerPoint presentation
to your team regarding the upgrade and the integration of the WATCH network into
SHGs Active Directory forest. Since your team is geographically dispersed, you
must create the slides and record the presentation so that when you distribute
it to your team, they can watch and listen to the recording to understand the
upgrade and integration.
You will need to do the following:
- Explain how to integrate the existing WATCH networking standards, protocols,
and access methods.
- Select which is the most appropriate protocols and access standard to use
without any loss of existing functionality to the billing department, the
intranet, or the existing Internet site.
- These functionalities will be migrated later, but for now your team needs
only the migration plans for the administrative and bookkeeping functions.
