Using the HP DHCP Settings Update Client Abstract Introduction Server Requirements This paper provides instructions for using HP DHCP Settings Update Client. The HP DHCP Settings Update Client is a utility that allows an IT Administrator to apply settings to an HP XP Embedded 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 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. The following sections provide a list of requirements for the DHCP Server and the FTP Server. DHCP Server Requirements FTP 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. 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. 2
