Server 2003: Event ID 53258 MS DTC

You may see this warning in your application event logs on Server 2003 domain controllers:

MS DTC could not correctly process a DC Promotion/Demotion event. MS DTC will continue to function and will use the existing security settings. Error Specifics: %1

The fix for this one is rather odd, as it doesn't require you to actually change anything, just open a dialog and hit OK, although it certainly changes something.

Open up Component Services from Administrative Tools. Expand Component Services, expand computers, right-click My Computer and click properties. Open the MSDTC tab and then hit OK. Strange, I know, but it works. You need to restart the Distributed Transaction Coordinator as well.
