VCC Utility Shared Resource Domain Model

Version: 1.2
Status: Approved 12/05/1999
Contact: Brendan L. Hogan

Purpose

The purpose of the Shared Resource Domain Model (SRD) is to define the process used to provide software distribution and allow VCCS operating units to access shared resources supported by the VCC Utility.

This SRD model covers connecting to shared resources and distributing software.

Applicability

The SRD model covers all operating units of the VCCS.

Definition

Provides automated software distribution.  Enables college administration of login ID’s and rights to shared resources.

Model

Certain resources such as the VCCS Student Information System (SIS), NETg SkillVantage, general software distribution, and future shared resources are shared between the colleges.  In an effort to leave user administration at the college level and resource administration at the Utility level, the SRD utilizes a Microsoft Multiple Master Secure Domain Model with a Resource Domain.  The SRD will be used to distribute software to campus-based servers.  Domain controllers are required at the colleges and Utility to provide authentication of users to shared resources.  All VCCS operating units will also maintain a fully replicated WINS database to provide for NetBIOS to IP translation.

Requirements

College Level

• College must install NT member server(s) in the UT domain.  Software will be automatically distributed and/or installed to this server.  This server may also function as an application server, i.e. PeopleSoft file server.
• Provide NT server loaded as Primary Domain Controller creating a domain for the college.  Colleges may choose to use an existing NT server.
• A Backup Domain Controller is recommended.
• All NT servers in this model should be kept at the same Service Pack level as determined by the Utility.
• A one-way trust must be established from Utility domain to each college domain.
• College will maintain NT Global Groups in their domain assigning appropriate users to those groups.
• Primary WINS service is required to provide NetBIOS name resolution.  Secondary WINS service is optional. Will replicate from VCC Utility hub WINS database.

VCC Utility

• Will provide a single resource domain named “UT”.
• Will maintain and assign resources by sharing to local groups.
• Will assign college global groups to these local groups.
• Will automatically distribute and/or install software to campus based file server(s) that participates in the SRD.
• Will provide hub WINS database.
