SYMPTOMS
When you automate the installation of Windows 2000 using the unattended installation method, you are unable to configure the Transport Control Protocol/Internet Protocol (TCP/IP) Internet Protocol security (IPSec) settings.



CAUSE
This issue occurs if IPSec parameters were not created for the Unattend.txt answer file used by the Unattend.exe utility.



RESOLUTION
To work around this issue, manually configure IPSec on the Windows 2000-based computer.



MORE INFORMATION
This section describes how to install IPSec and provides other related information.

NOTE: Before you configure IPSec to be used for communication between computers, you must test basic TCP/IP connectivity between the computers with a tool such as Ping.exe. Basic TCP/IP connectivity must be functioning before IPSec can be successfully implemented.  Add the IPSec Snap-in to the MMC:

 Click Start, click Run, type mmc.exe, and then press ENTER. Add IP Security Policy Management to the console, and then select Local Computer when prompted.  Create an IPSec Policy

 In the right pane, right-click IP Security Policy on Local Machine, click Create IP Security Policy, and then press ENTER.</li> Enter a policy name, and then press ENTER.</li> Accept the default settings for the Requests for Secure Connection screen by leaving the default response rule check box checked, and then click Next.</li> Accept the default response rule for Kerberos authentication, and then click Next.</li> Make sure the Edit Properties check box is checked, and if it is not, click to select it.</li> Click Finish. The properties box appears, do not close it.</li></ol> </li> Add a New Rule
