Note: The Windows Firewall feature of Windows XP SP2 is a replacement for the Internet Connection Firewall (ICF) in earlier versions of Windows XP.
Method 1: Restore the default security descriptor for the SharedAccess service
The service that controls the Windows Firewall/Internet Connection Sharing (ICS) service is named SharedAccess. The default security descriptor (SD) gives READ access to LocalSystem (SY), PowerUsers (PU), and AuthenticatedUsers (AU), and it gives Full Control access to Administrators (BA).
To view the SD of SharedAccess, type SC sdshow SharedAccess at the command prompt, and then press ENTER. The default SD appears and resembles the following:
D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;AU)(A;;CCLCSWRPWPDTLOCRRC;;;PU) |
Note: To open the command prompt, click Start, click Run, in the Open box, type CMD, and then click OK.
If you see any other output as illustrated in this example, you can reset the SD by using the SC command with the sdset option. To restore the default SD for the SharedAccess service, type the following command at the command prompt, and then press ENTER:
For more information about the SC sdset command, see Windows Help.
Method 2: Restore the default SD for the SharedAccess services.
Caution: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
To restore the default SD for the SharedAccess services, follow these steps:
- Click Start, click Run, in the Open box, type regedit, and then click OK.
- Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Security
- Delete the Security registry subkey, if it exists.
- Exit Registry Editor, and then restart the computer.
Note: It is important to delete the Security registry subkey if this subkey exists. This guarantees that the default security descriptor is used for starting Windows Firewall when the computer is restarted.
If you run Microsoft Component Object Model (COM), DCOM, or Microsoft COM+ applications to control the Windows Firewall service, you must also follow these steps:
- Click Start, click Run, in the Open box, type regedit, and then click OK.
- Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID\{ce166e40-1e72-45b9-94c9-3b2050e8f180}
- On the File menu, click Export.
- In the File name box, type C:eg_AppID_CLSID.reg, and then click Save to save the registry file.
- Delete the {ce166e40-1e72-45b9-94c9-3b2050e8f180} registry subkey.
- Click OK, and then exit Registry Editor.
- Start the Windows Firewall/Internet Connection Sharing (ICS) service. To do this, type NET START SharedAccess at the command prompt, and then press ENTER.
Note: You can perform all these steps at the command prompt. To do this, follow these steps:
- Type the following commands, and then press ENTER after each command:
REG DELETE HKLM\SYSTEM\CurrentControlSet\Services\SharedAccess\Security /fREG DELETE HKLM\SOFTWARE\Classes\AppID\{ce166e40-1e72-45b9-94c9-3b2050e8f180} /f
The deletion of the {ce166e40-1e72-45b9-94c9-3b2050e8f180} registry subkey is an important step. This step guarantees that the default security descriptor at the time of re-importing is applied. - Restart the computer.
