The Distributed Transaction Coordinator service terminated with service-specific error 3221229584
During a cluster maintenance where I removed one of the cluster nodes from the cluster and installed the SQL server as a standard standalone server I went in to problem to start the MSDTC. I got the specified error described above. It was quite simple to find out the solution. When paging thru the Registry I finded a path to the MSDTC log pointing to the old Qorum disk in the cluster. Just change this path and it works fine afterwards.
