A clustered instance of SQL server uses a cluster-wide MSDTC instance
instead of a local MSDTC instance on each host node. As such, the cluster
admin tool becomes the correct tool for managing MSDTC, not SQL Enterprise
Mangler. So, the behavior your DBA noted is correct for a cluster, but
since MSDTC is running the application will function correctly.

that she cannot start Distributed Transaction Coordinator on the node that
is NOT in control of the MSDTC resource using SQL Server Enterprise Manager.
This is on W2K3. This cluster will be replacing a W2K/SQL2K cluster. I
configured the W2K3 cluster, the same as the W2K cluster, yet she (the DBA)
CAN start MSDTC on either/both nodes of the W2K cluster. Why won't DTC
start on the other node in Ent Mgr? The DBA says that this is necessary for
something to function correctly, so I have to fix it? Any ideas/help would
be appreciated.
