Abstract

This paper provides instructions for using HP DHCP Settings Update Client.

Introduction

The HP DHCP Settings Update Client is a utility that allows an IT Administrator to apply settings to
an HP WES or XPe operating system. The settings are applied through an .INI file that uses a
subset of parameters from Microsoft's sysprep.inf as well as several WES/XPe/HP-specific keys.
XPePrep can run by specifying a local .INI file to be processed, or it can be used in conjunction with
DHCP and FTP servers to automatically apply settings across multiple clients on a network.

Server Requirements Linux Distributions

The following sections provide a list of requirements for the DHCP Server and the FTP Server.

DHCP Server Requirements

• Option 171 should contain a string value specifying an FTP server name. This can also be an IP
address, but must still be specified as a string (for example, 123.12.34.255).
• Option 172 should contain a String value specifying the path and filename for the input answer
file. This should be in the format of folder/filename.ini. If the file is located on the top directory,
then only the filename is required.
For example, if the answer file were stored in ftp://myserver/myfolder/xpeprep.ini, then DCHP option
171 should contain the string myserver and DHCP option 172 should contain the string
myfolder/xpeprep.ini.
If one of these values is changed on the DHCP server after clients have been updated, any clients
needing the new strings will either need to be rebooted or have the Microsoft DHCP Client Service
restarted. This is because DCHP options are cached locally on the client to increase performance.
However, this also prevents the client from seeing changes made on the server. Rebooting the
client will cause the cache to be refreshed to contain the new values. Restarting the DHCP service
will clear the cache so that requests will go to the server instead of the cache.

FTP Server Requirements

The FTP server must have a folder specified by DHCP option 172 that allows anonymous read
access or the server should have anonymous read access to the default folder (if no folder is
specified). Client input files should be placed in this folder.
