• Server Environment

2
Goals

• Improved accessibility to network resources
• Improved server network reliability
• Increased storage capacity for data
• Better utilization of resources
• Consolidation of resources
• Increased control over client workstations
• Increased security
• Disaster Recovery

3
Current Server Infrastructure

• 5 domains, each with separate user accounts,
  printers, workstations and purposes
• Lab
• Faculty Staff
• Web
• Payroll
• Proxy

4
Server Operating Systems

• All servers currently in production in our 5
  domains utilize Microsoft NT4.0 software
• Were in the process of migrating to Microsoft
  Windows 2000 Server.

5
Why upgrade to Windows 2000 Server?

• Advantages
• Active Directory integration
• Group Policy
• Automatic updates to clients
• Includes clustering technology
• Includes Terminal Services technology
• Many programs are not supported on NT 4.0, such
  as Exchange 2000
• NT 4.0 is no longer being supported by Microsoft

• Disadvantages
• Equipment upgrades to servers are necessary to
  support W2K Server
• Knowledge pool is smaller because the software is
  newer
• Requires the use of Microsoft XP on clients to
  fully utilize all features

6
Future Columbia College Server Environment

• Incorporates all 5 domains into 1 domain, with
  same users, workstations printers
• 1 Active Directory
• Group policy is used to control access to
  resources

Future Columbia College Server Environment
8
How do we get there?

• Upgrade workstations to Windows XP
• Migrate user accounts and workstation accounts
  from ccis_edu to ccis.edu
• Migrate printers from ccis_edu to ccis.edu
• Move user files and directories from old domain
  to new domain
• Join workstations to the new domain

9
Forestroot

• Forestroot is the first server in the forest
• It is a domain controller and a Global Catalog
  Server

10
MicrosoftExchange

• Exchange 2000 is the email portion of the new
  environment
• Serves all faculty staff, plus Distance
  Education students and ESD site staff
• Will eventually also serve Day students, Evening
  students and ESD students
• Windows 2000 Server is required to run Exchange
  2000

11
Backup

• Another member of the new domain is our backup
  server
• Handles daily backup of netfiles and server
  registries plus Exchange mail databases
• Is a Global Catalog server

12
DNS

• The DNS member of our new domain is installed and
  running
• This server handles the Domain Name Service for
  the domain.
• This server is also a Global Catalog Server

13
Terminal Services

• A new technology being introduced into this
  domain is Terminal Services
• This member of the new domain allows access to
  on-campus resources from off-campus

14
Webadvisor

• Webadvisor is the component of Datatel that
  allows web accessibility.
• Using Webadvisor, users will eventually be able
  to register pay for classes on-line, search for
  classes, look at transcripts much more
• Currently, there is a Webadvisor test server and
  a Webadvisor production server in the new domain

15
Proxy

• Proxy handles access to library resources from
  off-campus like EBSCOHost
• Proxy is in its own domain
• Eventually Proxy server will be upgraded to
  Windows 2000 and migrated to a new child domain.

16
Webserver

• Webserver hosts the Columbia College website
• Webserver is in its own domain (ccis_web)
• Eventually, webserver will be upgraded to Windows
  2000 and migrated to a new child domain
• Web.ccis.edu

17
Labserver

• Labserver is in its own domain ccislab
• Serves email to day evening students and
  controls access to printers in labs
• Will eventually be migrated to a new child domain
• lab.ccis.edu

18
Payroll

• Is currently in a domain by itself
• Will be migrated to a child domain of ccis.edu
• Ddsrv.ccis.edu

19
Other Server Projects

• Exchange Clusters/Network Load Balancing/Front-End
  /Back-End
• Will result in redundancy and high reliability
