Every day the Distributed Services support team in Microsoft helps customers in troubleshooting some of the most common Distributed Transaction errors which are a direct result of MSRPC (Microsoft Remote Procedure Call) communication failing in a network because of some Security\Firewall settings. On an application layer (like SQL), these are the common error messages that will be bubbled up.
- Server: Msg 7391, Level 16, State 1, Line 2 The operation could not be performed because the OLE DB provider 'SQLOLEDB' was unable to begin a distributed transaction. OLE/DB provider returned message: New transaction cannot enlist in the specified transaction coordinator.
- New transaction cannot enlist in the specified transaction coordinator (0x8004d00a)
- The transaction has already been implicitly or explicitly committed or aborted (0x8004d00e)
