Some difficulties came up today while trying to reinstall MSDTC.
Running msdtc -uninstall gave no result. In the eventlog, I found the following error:
I tried to manually stop the MSDTC service (Distributed Transaction Coordinator) in Services, but the error still popped up after running msdtc -uninstall.
The solution was quite stupid (and dumb at the same time): I had forgotten to run the command prompt as administrator. UAC was nagging me.
To verify your uninstall of MSDTC completed succesfully, open the Application log and note event 4105: The Microsoft Distributed Transaction Coordinator service was succesfully removed.
