Understanding the Process Flow The following steps explain the process shown in the above flowchart: 1. The system boots and launches the client from the Run key in the local machine registry or the user launches the client from command line, or by running Update Now from the client's Control Panel applet. 2. The client checks if a file was specified in the command line (e.g., xpeprep\test.ini). If the file is found, the client will check the SettingsVersion value and then process the file if needed. The following steps are performed: a. Delete the input file. b. Process the CommitEWF option. c. The client exits using the specified shutdown option. 3. The client looks for c:\xpeprep.ini. If the file is found, the client will check the SettingsVersion value and then process the file if needed. The following steps are performed: a. Delete c:\xpeprep.ini. b. Process the CommitEWF option. c. The client exits using the specified shutdown option. 4. If the file is not found, the client checks the DHCP settings. If DHCP is enabled and the DHCP server can be reached, the client will loop. It will try to contact the DHCP server for the FTP server and file path options based on the number of retries specified. Once the DHCP server has responded with the server and path names, the user will get the file from the FTP server and store it locally as c:\xpeprep.ini. The client will check the SettingsVersion value, and then process the file, if needed. The following steps are performed: a. Delete c:\xpeprep.ini. b. Process the CommitEWF option. c. The client exits using the specified shutdown option. If all other steps have failed, the client exists. 4

Understanding the Process Flow
The following steps explain the process shown in the above flowchart:
1.
The system boots and launches the client from the
Run
key in the local machine registry or the
user launches the client from command line, or by running
Update Now
from the client’s Control
Panel applet.
2.
The client checks if a file was specified in the command line (e.g.,
xpeprep\test.ini
). If the file
is found, the client will check the
SettingsVersion
value and then process the file if needed. The
following steps are performed:
a.
Delete the input file.
b.
Process the
CommitEWF
option.
c.
The client exits using the specified shutdown option.
3.
The client looks for
c:\xpeprep.ini
. If the file is found, the client will check the
SettingsVersion
value and then process the file if needed. The following steps are performed:
a.
Delete
c:\xpeprep.ini
.
b.
Process the
CommitEWF
option.
c.
The client exits using the specified shutdown option.
4.
If the file is not found, the client checks the DHCP settings. If DHCP is enabled and the DHCP
server can be reached, the client will loop. It will try to contact the DHCP server for the FTP server
and file path options based on the number of retries specified. Once the DHCP server has
responded with the server and path names, the user will get the file from the FTP server and store it
locally as
c:\xpeprep.ini
. The client will check the
SettingsVersion
value, and then process
the file, if needed. The following steps are performed:
a.
Delete
c:\xpeprep.ini
.
b.
Process the
CommitEWF
option.
c.
The client exits using the specified shutdown option.
If all other steps have failed, the client exists.
