I Do Not Have The Foggiest Notion Of How To Begin This And Need Some H

I do not have the foggiest notion of how to begin this and need some help. Following the scenario and the assignment directions, it has to be 10-20 slides in Microsoft PowerPoint and voice recording, but I would want detailed notes on the bottom of the slides instead of the recording, to get an idea of what I will actually record. It has to be done by tonight 02/09/2013 at 10pm. Scenario 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, SHG's 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 WATCH's 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. SHG's network is a Windows 2000/2003 network with Active Directory. The patient records application will eventually be merged into SHG's 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. Assignment: 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 SHG's 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.

Introduction

The integration of the Western Arizona Thoracic Care Hospital (WATCH) into the Southwestern Hospital Group (SHG) infrastructure represents a complex but crucial initiative to streamline operations, enhance patient care, and modernize hospital services. Given the distinct existing networks, protocols, and systems at WATCH, a strategic plan for migration and integration is essential to ensure continuous functionality, security, and seamless access for all departments. This paper discusses the approach to integrating WATCH's existing technological standards, selecting appropriate protocols and access methods, and developing a migration plan for the administrative and bookkeeping functions during the transition period.

Existing WATCH Network Architecture and Protocols

WATCH’s current network infrastructure features a mix of Windows NT and Linux systems, hosting critical services such as domain control, DNS, print services, and web hosting. The network comprises several domains: administrative, bookkeeping, billing, patient records, and nursing. Each domain operates using different protocols suited to their operational needs. The Windows NT domain primarily employs the Server Message Block (SMB) protocol for file sharing and authentication, while Linux systems utilize the Internet Protocol Suite (TCP/IP) with services like DNS and Apache web servers. Backup procedures rely on Automated Tape Library DLT Drives, with data spanning approximately 10 terabytes, housed predominantly on legacy systems, including an AS400 system containing roughly 7 terabytes of proprietary data.

Integration Strategies for Existing Standards and Protocols

To integrate WATCH into the SHG’s Active Directory environment effectively, compatibility at the protocol and standards level must be prioritized. The primary challenge is ensuring functional continuity, especially for the administrative domain (domain controllers, DNS, web services) and the bookkeeping domain (Oracle databases). A phased migration approach is advisable, beginning with establishing trust relationships between the existing NT domain and the SHG's Active Directory forest. This allows users from SHG to access WATCH resources with minimal disruption. The following strategies are recommended:

  • Establishing Trust Relationships: Implementing a two-way trust between WATCH's NT domain and SHG’s Active Directory ensures seamless resource sharing and authentication delegation.
  • Utilizing LDAP for Directory Services: Transitioning to LDAP-compliant directory services incrementally allows for easier integration and future migration to Active Directory features.
  • Protocol Compatibility: Maintaining SMB for file sharing and Windows-based services, while gradually introducing Kerberos authentication aligned with Active Directory, ensures minimal loss of existing functionality during the transition.

Selection of Protocols and Access Standards

The most appropriate protocol standard to ensure no loss of existing functionalities across departments involves a hybrid approach in which existing legacy protocols are preserved during the transition. Key considerations include:

  • File and Print Access: Continue utilizing SMB/CIFS protocols for Windows-based file sharing and printing services, as these are integral to administrative functions and user access.
  • Directory and Authentication Services: Integrate Kerberos authentication with Active Directory for secure and scalable login management, while retaining NTLM as a fallback temporarily.
  • Web Services: Maintain existing Apache HTTP servers for intranet and Internet sites, ensuring compatibility with existing browser standards and protocols.
  • Database Connectivity: Ensure seamless connection to Oracle databases and SQL Server systems via standard TCP/IP protocols to prevent interruption of bookkeeping and patient data management.

This hybrid approach allows the preservation of current services while gradually migrating to a fully integrated Active Directory environment, minimizing operational risks.

Migration Plans for Administrative and Bookkeeping Functions

The migration plan for administrative and bookkeeping functions should follow a phased approach to minimize disruption, ensure data integrity, and enable staff training. The key steps include:

  1. Pre-Migration Assessment: Conduct a comprehensive audit of current systems, data, and network configurations. Identify dependencies and potential integration issues.
  2. Trust Relationship Establishment: Set up trust relationships between the WATCH NT domain and SHG’s Active Directory.
  3. Incremental Data Migration: Migrate user accounts, group policies, and shared resources incrementally, starting with less critical systems to test configurations.
  4. Protocol Compatibility Testing: Ensure SMB, LDAP, and database connection protocols function correctly across the integrated environment.
  5. Training and Documentation: Provide support and training for administrative staff and end-users on new procedures and interfaces.
  6. Full Cut-over and Validation: Transition all administrative and bookkeeping services, validate functionality, and monitor performance.
  7. Contingency Planning: Prepare rollback procedures in case of critical failure, ensuring service continuity.

Conclusion

Integrating WATCH into SHG’s Active Directory environment requires careful planning, choice of compatible protocols, and a phased migration approach to preserve existing functionality. Maintaining legacy protocols such as SMB and TCP/IP connections during the transition ensures minimal disruption to operations. Establishing trust relationships and gradually migrating data and services enable a seamless transition with continued hospital operations. Future planned migrations will expand upon this foundation, ultimately creating a unified, secure, and scalable network infrastructure that supports WATCH’s modernization goals and SHG’s strategic vision.
