Important This article contains information about how to modify the registry. Make sure that you back up the registry before you modify it.

256986 Description of the Microsoft Windows registry



SYMPTOMS
When you use the Add/Remove Windows Components tool in Microsoft Windows Server 2003, you may experience one or more of the following problems:
 * The settings are empty for the TCP/IP port ranges for the DCOM protocols.
 * The Microsoft SQL Server service stops, and then the service does not automatically restart.
 * The Distributed Transaction Coordinator (MSDTC) cluster resource is displayed in the cluster administrator, even if MSDTC is not installed.

These problems may occur after you install a COM+ rollup package or a COM+ service pack.



CAUSE
These problems may occur if the Windows Components Wizard detects a version mismatch for MSDTC. When this behavior occurs, the Windows Components Wizard reinstalls MSDTC. The version mismatch occurs because the COM+ rollup package or the COM+ service pack does not update MSDTC version information in the registry.



WORKAROUND
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.To work around these problems, manually update the MSDTC version number in the registry to a larger number than the number of the MSDTC version that you have installed.

Note Also make sure that this number is larger than the number of any MSDTC version that you plan to install.

To do this, follow these steps:  Click Start, click Run, type regedit, and then click OK. Locate the following registry key, and then select this key:

 In the details pane, double-click MinorVersion, type in the Value data box, and then click OK.

Note In this example,  is the value of the minor version of the most-recently released hotfix.



Steps to reproduce the problem

 * 1) Install the latest COM+ 1.5 rollup package or the latest COM+ 1.5 service pack.
 * 2) In Control Panel, double-click Add or Remove Programs.
 * 3) Click Add/Remove Windows Components, and then click Next.

You may experience the problems that are described in the &quot;Symptoms&quot; section.
