INFO: Stand Alone Distributed Transaction Coordinator Setup

The stand alone setup program for the Microsoft Distributed Transaction Coordinator (DTC) allows customers to upgrade to the versions of the DTC that ship with the Windows NT 4.0 Service Packs (Service Pack 4 and greater) even if the service pack and/or the Windows NT 4.0 Option Pack (NTOP) is not installed.

Who Should Install This Release?

The recommended procedure for obtaining this release is to install the NTOP and then the latest Windows NT Service Pack. This release is for those customers that need the latest DTC version, but can not install either the NTOP or the latest Windows NT Service Pack. For example, you can use it to update DTC on a SQL Server 6.5 installation where for various reasons the operating system can not be modified.

You can install this release on all versions of Windows NT including Microsoft Cluster Server nodes. However, you should not install it on Windows 95 or Windows 98 computers.

Obtaining This Release

You can obtain this release from the following location:

Installing the Release on a Non-Clustered System

1. Download the proper Dtcsetup.exe for your computer (that is i386 or Alpha).
2. Make sure that you stop the Microsoft DTC service. Also, make sure that you stop any service that depends upon Microsoft DTC including Microsoft Transaction Server, Microsoft SQL Server, Microsoft Message Queue, and Microsoft COMTI.
3. Make sure that you close the Windows NT Control Panel.
4. Execute the Dtcsetup.exe file.
5. Restart the system.
6. Restart any services that depend upon Microsoft DTC.

Installing on a Cluster with an Existing Clustered Microsoft DTC

1. Download the proper Dtcsetup.exe for your computer (that is i386 or Alpha).
2. Make sure that you stop the Microsoft DTC cluster resource using the MSCS Cluster Administrator. Also, make sure that you stop any service that depends upon Microsoft DTC including Microsoft Transaction Server, Microsoft SQL Server, Microsoft Message Queue, and Microsoft COMTI.
3. Make sure that you close the Windows NT Control Panel on all systems in the cluster.
4. Execute the Dtcsetup.exe on the node that controls the Microsoft DTC cluster resource. When 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 file for your computer (that is i386 or Alpha).
2. Make sure that you stop the Microsoft DTC service on every system in the cluster. Also, make sure that you stop any service that depends upon Microsoft DTC including Microsoft Transaction Server, Microsoft SQL Server, Microsoft Message Queue, and Microsoft COMTI.
3. Make sure that you close the Windows NT Control Panel.
4. When you install this release on a clustered system, the setup program automatically installs 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, make sure that at least one such MSCS Resource Group exists. Dtcsetup.exe assigns 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 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.
