Understanding System Lock-down
Your administrator can configure whether or not to allow access to the Network Setup
dialog box to locally re-configured the thin client to operate in a different mode or to access
a different file server.
Note
High-privileged users always have access to the Network Setup dialog box.
During normal thin client operation, Low-privileged and Non-privileged users may access
the Network Setup dialog box by temporarily disconnecting the Ethernet cable from the
rear of the thin client and rebooting to Stand-alone user mode. The Network Setup dialog
box can also be accessed by a hot-key reset to factory default, in addition to the system
reset available to a Stand-alone user through the Sign-off/Shutdown/Restart the
System dialog box.
In most cases, access to normal operation resources is desirable. However, network
environments requiring maximum security typically do not permit uncontrolled changes to
thin client network operation. To achieve this security, the network administrator can place
a lock-down argument in any privilege statement (either in the user.ini file or in wnos.ini
file). This prevents Low-privileged and Non-privileged users from accessing the Network
Setup dialog box by resetting the thin client or through system restart to Stand-alone user
mode.
Caution
If a thin client accesses the enterprise intranet through Dial-up or PPTP and
the thin client is locked-down, a user attempting to reboot to Stand-alone
user mode will disable the Network Setup dialog box. The user will not be
able to re-access the enterprise intranet through this path. If this happens,
the thin client must be moved to a location where it can access the intranet
directly so that an administrator can set the profile to unlock the thin client.
If the thin client is configured for Dial-
up access, there must be an RAS
server answering the configured telephone number. Otherwise, the thin client
will require factory attention for recovery.
About the Session Services You Will Use
The desktop connection icons and Connect Manager list entries allow you to initiate
connections to servers providing ICA and RDP services. These services are configured by
the administrator for you to use. Depending on your privileges you can modify some of the
settings on these services. You can start connections by using the various Desktop or the
Connect Manager options made available by the administrator.
The Multiple Sessions feature allows the thin client to have multiple active connections.
The number of active connections you can have depends on the following:
• amount of RAM
• types of connections open
• number of connections configured
For more information on ICA connections, refer to "Configuring ICA Connections."

r more information on RDP connections, refer to "Configuring RDP Connections."
