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

 - Microsoft Transaction Server 2.0
---------------------------------------------------------------------

SUMMARY
=======

This setup program allows customers to upgrade to the version of the Microsoft 
Distributed Transaction Coordinator (DTC) that shipped with the Windows NT 4.0 
Service Pack 5 (SP5) even if the service pack and/or the Windows NT 4.0 Option 
Pack (NTOP) is not installed.

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

Who Should Install This Release?
================================
The recommended procedure for obtaining this release is to install the NTOP and 
then the SP5. This release is for those customers that need the latest DTC 
version, but can not install either the NTOP or SP5. For example, it can be used 
to update DTC on a SQL Server 6.5 installation where for various reasons the 
operating system can not be modified. 

This release can be installed on all versions of Windows NT including Microsoft 
Cluster Server nodes. It should not be installed on Windows 95 or Windows 98 
machines.

Obtaining This Release
======================

This release can be obtained from the following location:

ftp://ftp.microsoft.com/bussys/distapps/MTS/Public-Fixes/usa/DTC/SvcPack

Installing the release on a non-clustered system
================================================
1. Download the proper DTCSETUP.EXE for your machine architecture (i386 or Alpha).

2. Ensure that the Microsoft DTC service is stopped. Ensure that any services that 
depend upon Microsoft DTC are also stopped including Microsoft Transaction Server, 
Microsoft SQL Server, Microsoft Message Queue, and Microsoft COMTI.

3. Ensure that the Windows NT Control Panel is closed.

4. Execute DTCSETUP.EXE. 

5. Reboot the system.

6. Restart any services that depend upon Microsoft DTC.


Installing the release on a cluster with an already clustered Microsoft DTC
===========================================================================
1. Download the proper DTCSETUP.EXE for your machine architecture (i386 or Alpha).

2. Ensure that the Microsoft DTC cluster resource is stopped using the MSCS Cluster 
Administrator. Ensure that any services that depend upon Microsoft DTC are also 
stopped including Microsoft Transaction Server, Microsoft SQL Server, Microsoft 
Message Queue, and Microsoft COMTI.

3. Ensure that the Windows NT Control Panel is closed on all systems in the cluster.

4. Execute DTCSETUP.EXE on the node that controls the Microsoft DTC cluster resource. 
When you are prompted to install Microsoft DTC on the other nodes in the cluster, 
run DTCSETUP.EXE on those nodes. After doing this, reboot all systems.

5. Restart any services that depend upon Microsoft DTC.


Installing the release on a cluster with a non-clustered Microsoft DTC
======================================================================
1. Download the proper DTCSETUP.EXE for your machine architecture (i386 or Alpha).

2. Ensure that the Microsoft DTC service is stopped on every system in the cluster. 
Ensure that any services that depend upon Microsoft DTC are also stopped including 
Microsoft Transaction Server, Microsoft SQL Server, Microsoft Message Queue, and 
Microsoft COMTI.

3. Ensure that the Windows NT Control Panel is closed on all systems in the cluster.

4. When you install this release on a clustered system, the setup program will 
automatically install a clustered version of Microsoft DTC. The clustered version of 
Microsoft DTC requires a MSCS Resource Group that contains both a Network Name 
Resource and a Shared Disk Resource. Before installing this release, ensure that at 
least one such MSCS Resource Group exists. DTCSETUP.EXE will assign Microsoft DTC to 
the first MSCS Resource Group that it finds that contains both a Network Name Resource 
and Shared Disk Resource. After ensuring that the necessary Resource Group exists, 
execute DTCSETUP.EXE on the node controlling that Resource Group.

5. When you are prompted to install Microsoft DTC on the other nodes in the cluster, 
run DTCSETUP.EXE on those nodes. After doing this, reboot all systems.

6. Restart any services that depend upon Microsoft DTC.
