TITLE   :XCLN: Dr. Watson Crash When Windows NT Client is Installed
PRODUCT :Microsoft Exchange
PROD/VER:winnt:4.0
OPER/SYS:
KEYWORDS:kbsetup

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

 - Microsoft Exchange Server, version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When a user who is not a member of the local administrator group attempts to
install a Microsoft Exchange Client for Windows NT on a Windows NT Workstation
or Windows NT Server using the NTFS file system, and a local administrator has
never logged onto the computer and run the Microsoft Exchange Client Setup, the
setup process will get approximately 61% of the way through and then crash. The
following information, among other things, is displayed in the Dr. Watson log:

   Application exception occurred:
   App: [Pid number of occurrence]
   Time: [Time of occurrence]
   Exception number: c0000005 (access violation)

The access violation is the error.

The above information is only applicable when you attempt install from the .CAB
files. The symptoms are slightly different when you attempt to install from a
shared install point (created by an administrator running SETUP /A). In this
case, instead of receiving a Dr. Watson log, the user will receive a messagebox
informing them that the installation was unsuccessful but not giving a reason.

CAUSE
=====

When Windows NT is installed, the Mapi.dll file is installed into the
%WINNT%\SYSTEM32 directory with Read permissions (RX) for everyone, except the
members of the administrator group who have Full permissions. During
installation of the Microsoft Exchange Client for Windows NT, the Mapi.dll must
be upgraded and the rights to this file must be changed to Change rights (RWXD).
If the user attempting the install is not a member of the local administrators
group, this file cannot be upgraded nor can the rights be changed. This causes
the crash.

RESOLUTION
==========

The first user who attempts to install the Microsoft Exchange Client for Windows
NT on this computer must be a member of the local administrator group.

STATUS
======

Microsoft has confirmed this to be a problem in version 4.0 of the Microsoft
Exchange Client for Windows NT. We are researching this problem and will post
new information here in the Microsoft Knowledge Base as it becomes available.
