Hi I am having similar kind of error.

Unable to set the Publisher login for the updatable subscription. You may have to set this up directly on the Subscriber machine using sp_link_publication.

ADDITIONAL INFORMATION: An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)

The operation could not be performed because the OLE DB provider "SQLNCLI10" for the linked server was unable to begin a distributed transaction

No Transaction is active Error:7391

Please help
