The information in this article applies to:
- Microsoft Exchange Server 5.5
- Microsoft Exchange Server 4.0
- Microsoft Exchange Server 5.0
This article was previously published under Q154301 SYMPTOMS
When an X.400 connector is used over a slow link, a number of different
problems can occur. In some cases the message transfer agent (MTA) stops
responding and a DRWATSON log is generated with exception e0020002 or
Access Violation c0000005. One Application Event Log error is:
MTA error (Event ID = 9405):
An unexpected error has occurred which may cause the MTA to terminate.
Error: SBPDSCLS:CB TID=1,calling TID=0. [BASE TCP/IP DRVR 10] (16)
Other symptoms include the following socket errors:
A sockets error 10060
(WSAETIMEDOUT) event ID 9215, A sockets error 10051 (WSAENETUNREACH)
event ID 9215, A sockets error 10054 (WSAECONNRESET) event ID 9224.
WORKAROUND
The problem only happens when there is insufficient bandwidth or a high
number of network errors. One workaround is increase the bandwidth
available to the MTA.
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
Service Pack. For information on obtaining the Service Pack, query on the
