SYMPTOMS
The Microsoft Exchange Server MTA may raise an exception error on X.25 connections. Specifically, a RaiseException() may occur in the X.25 DMOD in the MTA.
CAUSE
RaiseException()is called from the MTA code when it receives an X.25 result for an X.25 control block (CB) that no longer exists. This condition should be handled by the MTA rather than causing the MTA to stop. The error handling was changed to remove the RaiseException() and add in a DebugBreak() for the debug build (in Ntil\Cc\Sbpdeccb.c).
The change allows the MTA to obtain more information the next time it happens with the debug build, and still does not stop normal running of retail builds.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 4.0.
This problem was corrected in the latest Microsoft Exchange 4.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base:
