KEYWORDS:kberrmsg

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows 98 Second Edition 
 - Microsoft Distributed Component Object Model (DCOM), version 1.2 
 - Microsoft Windows 95 
 - Microsoft Windows 98 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you start your computer without a network and then dynamically add a
network (by inserting a PCMCIA network adapter or by using Dial-Up Networking),
the first attempt to start a local COM server is unsuccessful if Distributed
Component Object Model (DCOM) is installed.

The underlying error message is detailed in the following table.

+-----------------------------------------------------+
| Type                     | Value                    | 
+-----------------------------------------------------+
| Standard Error Text      | Server Execution Failed  | 
+-----------------------------------------------------+
| Error Code (hexadecimal) | 0x80080005               | 
+-----------------------------------------------------+
| Error Code (decimal)     | -2146959355              | 
+-----------------------------------------------------+
| Error code (symbolic)    | CO_E_SERVER_EXEC_FAILURE | 
+-----------------------------------------------------+

CAUSE
=====

When there is no network, DCOM identifies the local computer using RPCSS with
the loopback address (127.0.0.1). When you dynamically add a network, remote
procedure call (RPC) does not detect the new Internet Protocol (IP) address
until it is reinitialized. However, COM initializes first and sends a request to
RPC to locate the local server. This does not trigger an RPC reinitialization,
and subsequent attempts to start the local server can succeed.


WORKAROUND
==========

To work around this behavior, start the client program a second time.

The following code sample shows how to bypass the problem programmatically:

   #include "stdafx.h"

   int fIsWin9X(void)
   {
       OSVERSIONINFO info;
    
       ZeroMemory(&info, sizeof(OSVERSIONINFO));
       info.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
       GetVersionEx( &info );
       if ( 4 == info.dwMajorVersion && VER_PLATFORM_WIN32_WINDOWS == info.dwPlatformId )
           return TRUE;
       return FALSE;
   }

   HRESULT myCoCreateInstance(
      REFCLSID rclsid,
      LPUNKNOWN pUnkOuter,
      DWORD dwClsContext,
      REFIID riid,
      LPVOID * ppv
   )
   {
       HRESULT hr = CoCreateInstance( rclsid, pUnkOuter, dwClsContext, riid, ppv );
       if ( CO_E_SERVER_EXEC_FAILURE == hr && fIsWin9X() )
           return CoCreateInstance( rclsid, pUnkOuter, dwClsContext, riid, ppv );
       return hr;
   }

STATUS
======

Microsoft has confirmed this to be a problem in Windows 95 and Windows 98 with
DCOM 1.3 installed.
