Classroom Setup

Network setup can take several hours. Be sure to allow adequate time
not only to set up the hardware and software, but also to test the setup.
As part of your testing, perform the hands-on exercises to ensure that the
structure you have created will allow students to successfully complete
the exercises.
Be sure to test your workstation display software (such as LANSchool)
with all NetWare programs that you plan to demonstrate. Some display
software is not compatible with some NetWare programs, particularly
NLMs such as INSTALL or NWCONFIG.
To set up the classroom, you

■

Set up the NetWare server

■

Set up basic Novell Internet Access SErvices (NIAS)

■

Set up NIAS remote access password security

■

Set up the lab workstations

■

Create student boot diskettes
