The export feature provides the ability to save a security database configuration as a new template file that can be imported into other databases, used as is to analyze or configure a system, or even redefined with the Security Templates console. To export security database settings to a security template, complete the following steps: 1. In the Security Configuration And Analysis console, right-click the Security Config uration And Analysis node, and then click Export Template. 2. In the Export Template To dialog box, type a valid filename in the File Name box, type a path to where your template should be saved in the Save In list, and select the type of file you want to save in the Save As Type list, and then click Save.

Administering Security with Group Policy
Security Configuration And Analysis Best Practices
The following are the best practices for working with Security Configuration And Analysis:
If you often need to analyze a large number of computers, such as with a domainbased infrastructure, use the Secedit command-line tool. Only use Security Configuration And Analysis to configure security areas not affected by local Group Policy settings. This includes areas such as security on local files and folders, registry keys, and system services. Otherwise, the settings config ured through Security Configuration And Analysis will override the local settings. Do not use Security Configuration And Analysis when you are configuring security for a domain or an OU. Otherwise, you must configure each client individually. In that case, you should use Security Templates to create a template and apply it to the appropriate GPO, or use the Security Settings extension to Group Policy to edit individual security settings on a GPO.
Security Configuration And Analysis Troubleshooting
Table 13-9 describes some troubleshooting scenarios related to security configuration and analysis.

Causes
Problem: The security database is corrupted. A hardware problem if the computer is improperly shut down or a software error. Run esentutl /g to check the integrity of the security database at %Systemroot%\Security\Database\Secedit.sdb If the database is corrupt, attempt to recover it by running esentutl /r on the %Systemroot%\Security folder. If this fails, attempt to repair it by running esentutl /p on %Systemroot%\Security\Database\Secedit.sdb. Then delete the log files in %Systemroot%Security. Use RSoP to check what GPO is affecting the computer. Check the log file, located in %Systemroot%\Security\Logs\ Winlogon.log, to identify specific errors that occur during policy propagation to the computer.
Problem: Security policy is not propagating correctly. Any

Solutions
Causes
Problem: Security policies are propagated, but the user receives an error message such as 0x534: No mapping between account names and security IDs was done. The security policy grants rights to user or group accounts that no longer exist. Find out which accounts are invalid. Open Microsoft Notepad and open the file at %Systemroot%\Security\Logs\Winl ogon.log. The Windows Server 2003 family and Windows XP create this file by default during policy propa gation. Search for error 1332, which indicates the account names that could not be resolved. Then remove the unre solved account names from policies in your domain. If the accounts are in the Default Domain or Domain Controller GPOs, you can edit the policies in the Security Set tings node of Group Policy to remove these account names. If the accounts exist elsewhere, you might have to browse through all GPOs defined in the domain and remove them individually.
Problem: The user receives an error message such as The system cannot log you on now because the domain <domain_name> is not available. The domain controller is unavail Ensure that the Interactive Logon: Number Of Previous
