I have a newly built SQL 2014 cluster which has me at my wit's end when trying to execute SSIS packages with "transactions required".Namely, I receive the following error when executing the SSIS package from dtexecui.exe or as a part of a job step:"The SSIS Runtime has failed to start the distributed transaction due to error 0x8004D027 "MSDTC was unable to read its configuration information.". The DTC transaction failed to start. This could occur because the MSDTC Service is not running. End Error DTExec: The package execution returned DTSER_FAILURE (1)."I googled until my eyes bled and tried just about everything I found. Made sure that:- Clustered DTC resource resolves via DNS- Under Security Settings for the clustered DTC, DTC network is enabled, remote clients are enabled, transaction manager communication Inbound and Outbound are enabled.- Testing distributed transactions from SSMS works:begin distributed transelect * from [linked_server].master.sys.sysdatabasescommitThis test correctly returns the remote server's list of databases and I see the committed and total transaction count increment in the Transaction Statistics under the Clustered DTC section of Dcomcnfg.exe. I use one of the instances on the same cluster as the remote linked server for the purposes of this test.I'm honestly stumped. Ready to provide any further info needed to resolve this. Please help!
