   Event ID   : 20103
   Source     : Router
   Description: Unable to load C:\WINNT\system32\ipxrtmgr.dll.

   Event ID   : 20133
   Source     : IPXRouterManager
   Description: The description for Event ID (20133) in Source
                (IPXRouterManager) could not be found.  It contains the
                following insertion string(s):.

   Source     : Service Control Manager
   Description: The Routing And Remote Access Service service terminated

CAUSE

When RRAS is installed on a multihomed server (one that has two or more network interfaces) and Auto Frame Type Detection is enabled for the NWlink IPX/SPX Compatible Transport, the bindings may not be correctly enumerated for the IPXRouterManager in the registry.

RESOLUTION

To resolve this issue, use the following steps:

Manually set the internal network number and specify Manual Frame Type Detection for the properties of the NWLink IPX/SPX Compatible Transport.
