Default Behavior

Certificate Propagation is a Win32 service. In Windows 7 it won't be started if the user doesn't start it. When the Certificate Propagation service is started, it is running as LocalSystem in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If Certificate Propagation fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the CertPropSvc service is not running because of the error.

Dependencies

Certificate Propagation is unable to start, if the Remote Procedure Call (RPC) service is stopped or disabled.

Restore Default Startup Configuration of Certificate Propagation

Before you begin doing this, make sure that all the services on which Certificate Propagation depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

2. Copy the command below, paste it into the command window and press ENTER:

sc config CertPropSvc start= demand

3. Close the command window and restart the computer.

The CertPropSvc service is using the certprop.dll file that is located in the C:\Windows\System32 directory. If the file is removed or corrupted, read this article to restore its original version from Windows 7 installation media.
