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.
