  • Article

Applies To: Windows Server 2008 R2

Event Details

Product: Windows Operating System
ID: 20071
Source: RemoteAccess
Version: 6.1
Symbolic Name: ROUTERLOG_PPPCP_DLL_ERROR
Message: The Point-to-Point Protocol (PPP) module: %1 returned an error while initializing.

Diagnose

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:

  1. Right-click rasppp.dll, and then click Properties.
  2. On the Securities tab, confirm that the SYSTEM account has read and execute permission and that read permission is set to Allow.

Resolve

Resolve

Check the availability of rasppp.dll

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.

Disconnect and retry the remote access connection, check network services, or check NAP

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.
