XADM: Corrupted IPX Packets Cause Information Store to Stop

Last reviewed: February 12, 1998
Article ID: Q177491
The information in this article applies to:
  • Microsoft Exchange Server, version 5.0

SYMPTOMS

A Microsoft Exchange Server version 5.0 information store may stop responding at random intervals with a Dr. Watson report similar to the following:

   Application exception occurred:
   App: Store.DBG (pid=240)
   When: 1/1/1997 @ 12:00:00.000
   Exception number: c0000005 (access violation)

CAUSE

The information store may have received a corrupted IPX packet from the network that caused the access violation.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server, version 5.0 Service Pack 1. This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 5.0. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces): S E R V P A C K

MORE INFORMATION

Windows NT does not support checksums for IPX packets, so rather than corrupt packets being dealt with at the network layer, this packet, with corrupt data, is being passed on to the information store. The information store cannot deal with this corruption and it stops.
