              About the
        University of Delaware

• One of the oldest land-grant institutions, as
  well as a sea-grant, space-grant and urban-
  grant institution.
• The University enrolls over 20,000 students.
• More than 7,000 students live on campus.
                   Why Sun Rays?
• We started evaluating Sun Rays to
  replace existing NCD X-Terminals.

• Sun introduced Sun Ray Connector
                                                                 Sun Ray 1G

• Allows Sun Rays to connect to Windows!

          WinSun Project
• We were supporting older PCs
  dedicated to providing limited
  services. “Express Station”
• Same level of support was
  needed                           Sun Ray 270

• Sun Connector software was a
  natural fit
                     WinSun Sites
• Smith Hall
   – Express terminals designed to provide quick
     access to Windows desktop functionality such
     as Office suite, web browsing and mail.
     This site also has full service desktop systems.
• Christiana
   – Full Windows desktop lab environment
     designed to provide Office suite, SPSS and
     Maple in addition to web browsing and mail.
     This site is in the commons area of a student
     dorm. Functions well as an unstaffed or
     minimally staff site.

In WinSun sites, all files are saved or edited from a USB key and
printed via VendPrint.                                         5
        Additional WinSun Sites

• Dickinson
  -The success of the Christiana site prompted
  User Services to convert another residence
  hall computing site to a WinSun site.
• Student Centers
  -At the request of the Student Government
  Association, two express stations complete
  with printing were deployed. One in the
  Perkins Student Center and one in the Trabant
  University Center.

                All-in-One Design

• Custom built cabinet
   – The University carpenter shop designed a
     cabinet for the station
• WinSun Terminal
   – For email, web browsing and to view and print
     documents, no editing
• VendPrint print release station
   – A Mac mini was used to minimize space

• HP 4240 LaserJet Printer

            WinSun Servers
         Software Configuration

Windows 2003 Server   Solaris 10 x86
Terminal Services     SRSS and Sun Connector
Mandatory Roaming     Kiosk mode script
Windows Firewall      Host allow-deny

           Windows 2003 Server
• This server should not be a Domain Controller.
   – Use Local Group Policy Object (LGPO)

• Terminal Services configuration
   – Use Terminal Services Configuration tool to configure Terminal

• Terminal server computer accounts
   – Domain accounts that reside in an OU (organization unit)
   – Accounts use a mandatory profile
   – Group policies are set on the OU

• Enable the Windows Firewall
   – Allow only designated machines access
   – Unblock applications as needed
  Solaris x86 Server Configuration

• Choose Kiosk mode for the SRSS configuration
• Default number of predefined kiosk users is 25
• Kiosk scripts are split so direct calls on the Solaris
  server do not show username and password
• Additional script needed for USB keys to be seen on
  the windows server
• All systems are denied access to the Solaris server
  except 1 for remote administration

• Network is mission-critical.
• USB devices not all recognized.
• Graphics-intensive applications put high
  demand on the network.
• Applications that use video and audio
  together do not perform well.

•   Reduced staff.
•   Ease of configuration and maintenance.
•   Reduced security/virus administration.
•   Reduced hardware failure.
•   Reduced power costs.

• Implemented three WinSun terminal sites.
• Students accepted the new technology.
• Students requested additional terminals in
  Student Centers.
• We continue to learn and discover best
  practices for this environment.
• “Proof of concept” has sparked increased
  interest around campus.
