Enable IPsec and Windows Firewall Audit Events

  • Articolo

Applies To: Windows Server 2008, Windows Vista

By default, Windows Firewall with Advanced Security does not generate audit events for either the Windows Firewall service or Internet Protocol security (IPsec). To see the events, you must enable event logging. Because the Windows Firewall and IPsec components can potentially generate a large number of events, consider turning logging on only when you need to troubleshoot Windows Firewall and IPsec issues, and then turn the events off again when you are done.

To perform these procedures, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority. If you do not have the required permissions, then the commands fail and display an error message.

To enable Windows Firewall with Advanced Security audit events

  1. Open an administrative command prompt. Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

  2. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.

  3. At the command prompt, type the following command. You can copy and paste this command into the Command Prompt window:

    auditpol.exe /set /SubCategory:"MPSSVC rule-level Policy Change","Filtering Platform policy change","IPsec Main Mode","IPsec Quick Mode","IPsec Extended Mode","IPsec Driver","Other System Events","Filtering Platform Packet Drop","Filtering Platform Connection" /success:enable /failure:enable

  4. Restart the Windows Firewall service by typing the following commands, ending each by pressing ENTER:

    net stop MPSSVC

    net start MPSSVC

  5. When you are ready to disable event logging, run the same command as in step 3, but use /success:disable /failure:disable at the end of the command. Then restart the service by performing step 4 again.
