Cluster Management. In the left pane expand the Services and Application group and
select the MS-DTC resource. From the summary window note down the Server

can be verified by opening the disk in the windows explorer. Now we should be
able to see the MSDTC folder inside the new drive which confirms the
movement.
Bring this
service online. Set the preferred owner through the properties window and test
the failover.
