The Windows Firewall Service Can Not Start
After installing Windows XP Service Pack 2 or 3, the Windows Firewall service will not start. Problems with the
Genie camera or Framework may include:
• The Genie camera cannot acquire a DHCP address
• Registry writes fail
• Messages in the Sapera Log Viewer include "check your firewall" and the computer firewall is disabled for no
reason.
After installing Windows XP Service Pack 2 or 3, the Windows Firewall service will not start. Symptoms may
include the following messages:
• When you click Windows Firewall in Control Panel, you may receive the following error message:
Windows Firewall settings cannot be displayed because the associated service is not running. Do you want to
start the Windows Firewall/Internet Connection Sharing (ICS) service?
• If you try to manually start the Windows Firewall service by using Services, you may receive the following
error message:
Could not start the Windows Firewall/Internet Connection Sharing (ICS) service on Local Computer.
Error 0x80004015: The class is configured to run as a security id different from the caller.
These symptoms are described in detail by Microsoft support at this link (
http://support.microsoft.com/kb/892199).
Without covering the details mentioned in the Microsoft support web page, the solution involves deleting two
registry keys in the host computer. This procedure should only be done by someone comfortable with Windows
registry backups and editing. These registry keys can be deleted via the following command console instructions:
• REG DELETE HKLM\SYSTEM\CurrentControlSet\Services\SharedAccess\Security /f
• REG DELETE HKLM\SOFTWARE\Classes\AppID\{ce166e40-1e72-45b9-94c9-3b2050e8f180} /f
Reboot the computer after execution.
