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

- Microsoft Exchange Server, version 5.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Exchange 5.0 Setup requires Service Pack 5 to be installed on Windows NT Server
version 3.51 or Service Pack 2 installed on Windows NT Server 4.0.

After you install Windows NT 4.0 Service Pack 2 on a Dual Processor Compaq System
with a Compaq SSD installed, the system may stop responding (hang) at the
Windows NT logon screen, without displaying any error messages.

CAUSE
=====

The Compaq SSD was used to upgrade the system to a multi-processor system. The
SSD correctly installs the files required for multi-processing support but
incorrectly modifies the line in the Setup.log file that refers to Hal.dll. The
Hal.dll line references the single processor version of Hal.dll, and the
NTOSKRNL line references the multi-processor version of the kernel. As a result,
the Windows NT Service Pack installs the multi- processor kernel file and the
single processor version of Hal.dll.

When the system restarts after the service pack installation, the Windows NT
Kernel Load screen reports one system processor - the multiprocessor kernel.
Windows NT continues loading but stops responding at the logon screen without
any errors.

WORKAROUND
==========

Please refer to Knowledge Base article Q162250, "Service Packs on Compaq MPS
Systems May Cause System Hangs," for a workaround and more details.

MORE INFORMATION
================

The Microsoft Exchange Server 5.0 Upgrade student guide shows an incorrect error
message on pages 2-8. This error message states that the minimum requirement is
Windows NT 4.0 [Build 138 Service Pack 1].
