SUMMARY

When you install Microsoft Transaction Server (MTS) 2.0 on a computer that is running Microsoft Windows 98, the Microsoft Distributed Transaction Coordinator (MS DTC) is also installed. MS DTC is set to start automatically when Windows 98 starts. MS DTC is a service that coordinates distributed transactions and must be running in order to use MTS transactions.

However, you may want to start Windows 98 without MS DTC starting automatically. This article describes how to disable the automatic startup of MS DTC.

MORE INFORMATION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To disable the automatic startup of MS DTC, use the Registry Editor (Regedit.exe) to delete the MSDTC registry string value under the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices

To enable the automatic startup of MS DTC, use the Registry Editor (Regedit.exe) to create a registry value named MSDTC with the msdtcw -start value under the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices

Although Windows 98 does not support true Windows NT type services, it can load service-like applications at startup. The Run, RunOnce, RunOnceEx, RunServices, and RunServicesOnce keys are designed for this purpose. For more information about the effect of using these keys, see the "References" section.
