Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
To restore the default SD for the SharedAccess services, follow these steps: 1. Click Start, click Run, in the Open box, type regedit, and then click OK.
2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Security
3. Delete the Security registry subkey, if it exists.
4. Quit 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 perform the following steps: 1. Click Start, click Run, in the Open box, type regedit, and then click OK.
2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID\{ce166e40-1e72-45b9-94c9-3b2050e8f180}
3. On the File menu, click Export.
4. In the File name box, type C:\reg_AppID_CLSID.reg, and then click Save to save the registry file.
5. Delete the {ce166e40-1e72-45b9-94c9-3b2050e8f180} registry subkey.
6. On the File menu, click Import.
7. In the File name box, type C:\reg_AppID_CLSID.reg, and then click Open.
8. Click OK, and then quit Registry Editor.
9. Start the Windows Firewall/Internet Connection Sharing (ICS) service. To do this, type NET START SharedAccess at the command prompt, and then press ENTER.
