If symbols are loaded, the Dr. Watson log normally indicates that an exception error occurred in the EMSMTA!oxpufret function, often at memory location 02199613. CAUSE ===== The Microsoft Exchange Server MTA may cause the exception error when a failure is returned when it requests dialup or protocol information. The MTA may attempt to access the information once the information has been nulled out, causing the exception error. STATUS ====== Microsoft has confirmed this to be a problem in Microsoft Exchange Server versions 4.0 and 5.0. This problem was corrected in the latest Microsoft Exchange 4.0 U.S. Service Pack.
