      Joe Braly,

      This response is in regards to a service, MSGSRV32.EXE,
      running, as you say, "in the backround." I have had some
      experience with this and researched its functionality. First, it
      should ALWAYS be running. Second, it should NOT be interfering
      with anything on your computer and should not be using anything
      but a MINUTE amount system resources.

      MSGSRV32.EXE is used at boot-up and shutdown times to
      perform hardware checks for the most part. It is a necessary
      component for Windows 95, 98 and 98SE (uncertain about other
      flavors of Windows) to run. I once worked on acomputer that
      MSGSRV32.EXE complained on shutdown, every time. It was failing
      a call to a Creative Technologies Sound Blaster PnP file. I
      renamed the file, the sound card still worked fine and the
      computer went back to a normal shutdown. If MSGSRV32.EXE errors
      on your computer, look at what it says is complaining TO it (by
      clicking on DETAILS). That is a significant piece of information
      you need to ascertain. I have no idea why this particular Sound
      Blaster file was being called to by MSGSRV32.EXE. It was not my
      computer, I was fixing someone else's.

      On the very same computer, I must add, the wrong amount of
      RAM was being detected at boot up. That turned out to be a
      reseat of the RAM memory module. I still wonder if that played a
      role in the above matter. I understand that RAM failures are 1)
      hard to detect and 2) can cause all sorts of very strange

      I also saw this description on the web:

      MSGSRV32.EXE is a Windows 32-bit VxD Message Server. For
      more information on its function and why it's needed, see here
      {MS Knowledge Base article below}. Note - why some people have it
      listed in start-up programs I don't know but I was asked to
      include it here. It automatically runs in the background.

      Microsoft Knowledge Base Article - Q138708
      Function of the Windows 32-Bit Message Server
      The information in this article applies to:
      Microsoft Windows Millennium Edition
      Microsoft Windows 98
      Microsoft Windows 95


      This article describes the purpose of the Windows 32-bit message
      server (Msgsrv32.exe).


      Msgsrv32.exe is a program that runs invisibly on the Windows
      desktop and performs several background functions necessary for
      Windows operation. These functions include:

      Mediate Plug and Play messages among various parts of the
      operating system.
      Coordinate automatic responses to Setup programs. This includes
      checking whether a Setup program has improperly overwritten
      Windows files, and optionally restoring the Windows versions of
      those files.
      Display the initial logon dialog box if networking is enabled.
      Play the system startup and shutdown sounds.
      Load installable Windows drivers at startup and unload them at
      Run the shell program (usually Explorer.exe) and re-run the shell
      if it fails to respond.

      I hope this is of some help to you. Let us know if you
      indeed find the underlying cause. Good luck.

      Kind regards,
      Christopher J. Spilker
