Could not start Distributed Transaction Coordinator on a clustered server.

I am trying to start Distributed Transaction Coordinator in one of the node of my clustered server.
It is running in Windows Server 2003 Enterprise Edition. But I received the error mesage as stated in the Error Messges tab.

How can I resolve this problem?

Although it's not a solution but a workaround, try to see if this one should work for you:

- Select the MS DTC resource, right click and select properties;
- Check the Run this resource in a separate Resource Monitor option;
- Move the group that contains the MS DTC resource to the node that you encounter the problem and check if the resource goes online.

eer, the MSDTC is running locally on individual node.
If you mean they are to be clustered, please elaborate on how to?

Well MS DTC must be clustered in presence of application in cluster like SQL.

Microsoft's Best Practices indicates that DTC must reside in it's own group (and therefore depend from it's own Network Name and volume resource). In a real world scenario, where Storage space and LUNs are not infinite (and neither buIT budget is), the solution is to cluster DTC in the quorum group.
Be sure that in each node is installed the following Windows Components (from Control Panel/Add Remove Programs/Add Remove Windows COmponents/Application Server) Enable Network COM+ Access.

You must select the quorum group, right click, New and select New Resource; the new resource type must br Transaction Distributor Coordinator; add a name (like MSDTC). Follow the wizard and add as dependencies the Network name and the Volume resources. That's it. After that you must restart the the clustered applications (SQL ecc) or do a move group.

Test the DTC functionality and in case there's an error bringing online the resource do the following:

Select the MS DTC resource, right click and select properties;
- Check the Run this resource in a separate Resource Monitor option;
- Move the group that contains the MS DTC resource to the node that you encounter the problem and check if the resource goes online.
