MSDTC Event ID 4143 and 53258 on Windows Server 2003 SP1 Domain Controller

I got hit by a problem on a freshly installed virtual machine using a slipstreamed SP1 installation and promoted to a domain controller. Two events were appearing in the event log which were unexpected.

Source: MSDTC Event ID: 53258 Warning
MS DTC could not correctly process a DC Promotion/Demotion event. MS DTC will continue to function and will use the existing security settings.

To resolve this, go through the following steps:
- Start/Administrative Tools/Component Services
- Navigate the tree view on the left to:
– Console Root
– Component Services
– Computers
– My Computer
- Right click on „My Computer” and select properties
- Select the MSDTC Tab
- Under „Transaction Configuration” near the bottom, click „Security Configuration”
- On the Security Configuration screen, just click OK – don’t change anything.
- Back on the „My Computer Properties” screen, click OK again to dismiss
- Right click on „My Computer” in the tree view and select „Stop MS DTC”
- Right click on „My Computer” in the tree view and select „Start MS DTC”
- Close the Component Services snapin.

All should now be well again. Hope this helps someone.
