How to reinstall the Microsoft Distributed Transaction Coordinator on a computer running Windows XP

to extract the steps here:

This article describes how to reinstall the Microsoft Distributed Transaction Coordinator (MS DTC) on a computer that is running Microsoft Windows XP.

More information

Generally speaking, you do not have to reinstall the Microsoft Distributed Transaction Coordinator (Msdtc.exe) on computers running Windows XP or later. If you are using an older operating system, you may have to reinstall MS DTC after you install software such as Microsoft SQL Server 6.5, because the software overwrites the MS DTC binaries with the version it contains. Reinstall the correct version of Msdtc.exe to restore the binaries. In Windows XP and later versions, the Windows File Protection (WFP) feature ensures that the current system binaries are not replaced.

However, if you must reinstall MS DTC on the computer that is running Windows XP, use the following procedure.

Warning: If you use the following steps, all outstanding transactions will be lost. Make sure that there are no active transactions before performing the following steps.

Warning: Improper use of Registry Editor can cause serious problems that may require you to reinstall your operating system. Microsoft does not guarantee that you can resolve problems caused by improper use of Registry Editor. Using Registry Editor requires your own risk.
1. In Administrative tools, open services, and then stop all services.
2. In the Startup Type column, change the startup type of all other services to manual, in addition to the services in the following table.

Attention: It is recommended that you write down the service that you changed so that you can restore the values correctly in step 7.

8. In the registry, create the following registry key:
9. At the command prompt, type regsvr32 mtxoci.dll.
