Network Computer Service Diagnostics

This tool checks the health of each of the critical network services that are required to boot and run a network computer (NC). It also validates advanced DHCP service.

The network services checked are:

• TFTP

• NFS

• DHCP

• NIS

• DNS

• HTTP

This tool checks that the service is running, that it is up, and that the configuration files are OK.

To Check the Status of All Network Services

1. From the Main Administration Page, under "Network Computer Administration," click Network Computer Diagnostic Tools.

To Validate Advanced DHCP Service

The Advanced DHCP Diagnostic emulates the broadcast of a DHCP DISCOVER request from a particular NC and captures the response from every DHCP server that replies. From this list we can determine whether the local DHCP server is responding properly and if there are any other DHCP servers errantly responding to our requests.
