    TITLE:  Error After Enabling Desktop Management

    ISSUE

       On a Bravo MS system with LANDesk Client Manager (LDCM) 3.0
       installed, when the Microsoft 'Desktop Management' System
       Management Services are ENABLED, a Fatal Exception Error may
       occur in VWIN32 (or other listed errors may occur) following a
       reboot. This issue applies to all Bravo MS systems running
       Windows 95

       To access Desktop Management, click the following:

          Control Panel
          Add/Remove Programs
          Windows Setup
          Accessories
          Desktop Management

       This issue affects the following systems: 503190, 503191, 503192,
       503246, 503247, 503248, 503250, 503251, 503320, 503321, 503322,
       503323, 503340, 503415, 503416, 503417, and 503418.

    BACKGROUND

       When Microsoft Desktop Management is ENABLED, DMIAPI32.DLL is
       copied into the WINDOWS\SYSTEM folder.  This .DLL file includes
       the same function names which are included in the DMIAPI32.DLL
       installed by LDCM 3.0, DmiIndicate and DmiInvoke.

       The LDCM 3.0 modules will access the functions in the newly
       installed .DLL, rather than the functions in the DMIAPI32.DLL
       file in the DMI\WIN32\BIN folder. Errors occur because the
       function implementations are not equivalent.

       The errors vary somewhat depending on the system and your
       configuration. They may include one or more of the following:

          (Blue Screen)
          A Fatal Exception Error has occurred at 0028:C027C93A
          in VxD VWIN32... The current application will be
          terminated... Press any key to continue.

          Illegal operation on CILM78. Invalid Page Fault in
          module unknown at 0000:0064F2F6

          LDFxOS 32 bit LDCM File/OS Instrumentation Could not
          register with service layer Retry limit reached.
          Instrumentation will terminate.

          Configuration Manager could not load because one of
          the following files is not present or has an invalid
          version number. VMM.VXD SHELL.VXD VTD.VXD VXDLDR.VXD
          VPICD.VXD

          Windows could not combine VxD's into a monolithic file
          before starting. Windows may not start or run
          properly. If Windows fails to start, run SETUP again.
          Press any key...

    ACTION

       To resolve the issue, perform the following steps:

       1. Reboot the system.

       2. When the screen displays 'Starting Windows 95', press
          the [F8] key.

       3. Select 'Safe Mode'.

       4. Remove the check mark from Control Panel | Add/Remove
          Programs | Windows Setup | Accessories | Desktop
          Management.

       5. From Explorer, delete the the following file, if it
          exists:

             C:\WINDOWS\SYSTEM\DMIAPI32.DLL

       6. Restart the system.
