XADM: Batch Export Crashes When Non Zero ulUSNBase is Specified

The information in this article applies to:

• Microsoft Exchange Server, version 5.0

SYMPTOMS

When you run a batch export in Microsoft Exchange Server, version 5.0, the Directory Service may abort operation.

CAUSE

If BatchExport is called with non-zero ulUSNBase, the data structure used to build the filter object for passing to the Directory Service is missing a field (size). This causes the filter to be built with a NULL value, which results in an error on the ds_search. The error handling routines then attempt to access the current Attribute/Value tables, which don't exist for BatchExport.

This behavior will not occur when you use the Microsoft Exchange Administrator program. The export command in the Administrator program does not provide an option to set the ulUSNBase to not zero.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.0. This problem was corrected in the latest Microsoft Exchange Server 5.0 U.S. Service Pack.
