This error might be caused by one of the following conditions:
- The Routing and Remote Access service is unable to start because the PPP protocol was not initialized. This might have occurred for one of the following reasons:
- The remote access service failed to load rasppp.dll. See the section titled "Check the availability of rasppp.dll."
- The remote access service failed to load the entry\exit function of PPP.
- Incorrect configuration or lack of resources. See the section titled "Disconnect and retry the remote access connection, check network services, or check NAP."
- The Routing and Remote Access service is unable to initialize the RPC service.
- The dynamic-link library (DLL) did not implement one of the following functions: RasCpInit, RasCpEnumProtocolIds, RasCpGetInfo, RasEapGetInfo.
Check whether the SYSTEM account has read and execute permissions for the file %systemroot%\system32\rasppp.dll.
To check the permissions of the SYSTEM account:
- Right-click rasppp.dll, and then click Properties.
- On the Securities tab, confirm that the SYSTEM account has read and execute permission and that read permission is set to Allow.
Confirm that rasppp.dll exists at %systemRoot%\system32. If the dynamic-link library (DLL) does not exist at this location, you might need to repair or reinstall the Windows operating system.
Possible resolutions:
- Disconnect and retry the remote access connection.
- Check that network services such as firewall services, NAP Agent, antivirus, system health validators (SHVs), and system health agents (SHAs) are running.
- Make a Network Access Protection (NAP) connection, change the statement of health (SoH), and then check if the issue still exists.
