JSI Tip 4856. RRAS won't start and Event Id 20103 is logged?

After you configure the Routing and Remote Access Service (RRAS), it does NOT start and the System event log contains:

Event ID: 20103 
Source: Router 
Description: Unable to load C:\Winnt\System32\Iprtrmgr.dll
If use the Routing and Remote Access service management console to view the Ports container, the available ports may not be displayed.

To resolve this problem, troubleshoot:

1. Use Regedt32 to verify that the following keys / values exist:


      Value name: DLLPath 
      Data type:  REG_EXPAND_SZ 
      Value data: %SystemRoot%\System32\Iprtrmgr.dll 

      Value name: GlobalInfo 
      Data type:  REG_BINARY 
      Value data: The data varies between computers 

      Value name: ProtocolID 
      Data type:  REG_DWORD 
      Value data: 0x21 (Hexadecimal)
2. Verify that Iprtrmgr.dll exists at the specified location.

3. If all the above are correct:

      Disable the service.

      Uninstall the modem using Device Manager.

      Restart the server and let Plug and Play detect the modem. 

      Enable the Routing and Remote Access service.
4. If the problem is not resolved, see tip 4797.
