When you try to start a transaction from a COM+ component on a clustered Microsoft SQL Server server, the transaction does not start. When this occurs, the following error message may be logged in the event log:
Event Type: Error
COM+ application identities must be in the Administrator group on Microsoft Cluster Server (MSCS) clusters. For COM+ applications on MSCS clusters, the user account that is associated with the application identity must be a System Administrator account or must have Full Control cluster access permissions as set in the Cluster Administrator (Cluadmin.exe). If you do not use a System Administrator account to run the package, the COM+ application cannot connect to the Microsoft Distributed Transaction Coordinator (MSDTC).
