HP t5630 Using the HP DHCP Settings Update Client - Page 7

Best Practices HP recommends the following best practices when configuring the HP DHCP Settings Update Client. Best Practice Explanation If you apply a computer name change, the Shutdown option in XpePrep should equal Shutdown or Reboot, and the CommitEWF option should be set to Yes. Changing the computer name requires a reboot in order to take effect. If you apply a computer name change and do not commit the change to the EWF protected volume, the name change will be lost during the reboot. If you select Yes for CommitEWF, the Shutdown option should be set to Reboot or Shutdown. Data in the EWF overlay is not committed to the protected volume until the system shuts down. Any changes made to the system after the HP DHCP Settings Update Client runs (and commits the EWF overlay) will be saved. If you select No for CommitEWF, then you should not set the Shutdown option to Reboot or Shutdown. The recommended setting is None. If the EWF Overlay is not committed to the protected volume, then the client will not preserve the SettingsVersion. This will cause the client to process the settings and apply the Shutdown option every time a user logs in. This would put the system in an endless loop of booting, logging-in, and rebooting. If you do not specify a SettingsVersion, or the SettingsVersion is set to 0, then you should not set the Shutdown option to Reboot or Shutdown. The recommended setting is None. Not specifying the SettingsVersion, or setting it equal to 0 will cause the client to always apply the settings and process the Shutdown option. This would put the system in an endless loop of booting, logging-in, and rebooting. If you change the password on the Administrator account, then the computer name changes will only be applied when users with administrative privileges logon to the machine. Changing the computer name requires administrative access. The client depends on impersonating the Administrator account in order to apply computer name changes when running as a "Guest" user. For security reasons, a method of communicating a password change to the client has not been established. In order to process the CommitEWF or Shutdown options, other settings must be specified. These options will not be processed unless other settings have been specified. This is done to ensure that there are no unnecessary reboots or writes to the flash storage media. 7
