It is my understanding that when having LinkedServers, the option "enable promotion of Distributed Transactions for RPC" should be set to TRUE, so we can rollback , if needed, remote transactions. At least, that's my understanding of that setting.
Having said that, the TRUE setting is affecting this particular TSQL code, inside an sproc, which I would prefer not to alter:
Insert into #TempTable
When set is set to TRUE (current setting) I get this error:
OLE DB provider "SQLNCLI11" for linked server "ServerB" returned message "The partner transaction manager has disabled its support for remote/network transactions.".
Msg 7391, Level 16, State 2, Line 28
The operation could not be performed because OLE DB provider "SQLNCLI11" for linked server "ServerB" was unable to begin a distributed transaction.
... when set to off, the error goes away.
Can someone help me to understanding this behaviour? Please don't send me to BOL. I want real life answer from other DBAs. I don't want to change to off just to fix this, if it will potentially affect distributed transactions or , if there is a TSQL workaround that is is easy to implement.
