SYMPTOMS

When you try to change the size of the Microsoft Distributed Transaction Coordinator (DTC) log file in Microsoft Windows Server 2003, the size of the DTC log file does not change.

Note This problem occurs when you run the DTC in a cluster environment.

CAUSE

This problem occurs because of the way that the DTC handles cluster node names. If the DTC cluster node name contains more than or fewer than 15 characters, the name is read incorrectly and the size of the log file cannot be changed.

WORKAROUND

Important This article contains information about how to modify the registry. Make sure to back up the registry before you modify it. Make sure that you know how to restore the registry if a problem occurs. For more information about how to back up, restore, and modify the registry, click the following article number to view the article in the Microsoft Knowledge Base:

256986 Description of the Microsoft Windows registry


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 your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To work around this problem, create a new script file to change the DTC log file size value in the Microsoft Windows registry:

  1. Click Start, point to All Programs, point to Accessories, and then click Notepad.

  2. In the Notepad window, add the following code:
