Default Behavior

Certificate Propagation is a Win32 service. In Windows 8 it will not be started until the user starts it. When the Certificate Propagation service is started, it runs as LocalSystem in a process of svchost.exe, sharing it with other services. If Certificate Propagation fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the CertPropSvc service hasn't been started.

Dependencies

Certificate Propagation can't start, if the Remote Procedure Call (RPC) service is disabled or not available.

Restore Default Startup Configuration for 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 %WinDir%\System32 folder. If the file is corrupted or deleted, you can put it back in there.
