Product: Exchange
Event ID: 1128
Source: MSExchangeMTA
Version: 6.5.6940.0
Component: Microsoft Exchange Message Transfer Agent
Message: An interoperability error occurred with entity <object name>. A reliable transport service element (RTSE) error occurred. RT-U-Abort was received but not supported in X.410 1984 mode. Control block index <index name>. [<value> <value> <value> <value>] (14)
   
Explanation

The RT-U-ABORT service enables an RTSE-user to end the application-association.

The Reliable Transfer Service is provided in two modes of operation, namely, the X.410-1980 mode, which is provided solely to allow interworking with older implementations based on CCITT Recommendation X.410-1984 and which implies some restriction in the use of RTSE services; and the normal mode, which is provided to allow full use of RTSE services. This event indicates that the message transfer agent (MTA) that is logging the event is operating in a mode that does not support the RT-U-Abort service.

   
User Action

The diagnostics logging levels of the message transfer agent (MTA) interface and interoperability categories should be increased to create interoperability logs. These logs are text logs that consist of the binary contents of communication among MTAs in different sites, and between MTA and client applications within a site. They are stored in the \Exchsrvr\Mtadata directory. The current log is always named Bf0.log. Prior logs are named Bfx.log, where x increases as the age of the log increases.

To help Microsoft Product Support Services determine the problem, create log files. For more information, see Microsoft Knowledge Base articles 163032 and 168906.

To create Ap*.log files, on the Diagnostics Logging tab of the Server Properties dialog box, select MSExchangeMTA, and then set the logging level of the Interoperability and Interface categories to Maximum.

To create Bf*.log files, set the logging level of the Application Protocol Data Unit (APDU) and X.400 service categories to Maximum.

Save all MTA log files (mtadata\*.log), Event Viewer output, and database files. Contact Microsoft Product Support Services for assistance.
