ACC: Network Problems May Cause "Segment Load Failure" Error, "System Process - Lost Delayed Write Error" Error or "Invalid Bookmark" Error

You receive a "Segment Load Failure" error message or another memory- conflict error message.

In Microsoft Access 97, you may also receive a "System Process - Lost Delayed Write Error" or an Invalid Bookmark Error message when viewing data from linked tables.


A "Segment Load Failure" error message can occur if Microsoft Access is running on a network or is accessing data on a network, and the network server stops functioning correctly.

A segment load failure implies that there was a problem moving information from secondary storage, such as a network server disk, to main memory. If a network server stops functioning correctly, expected information may not be available to Microsoft Access.

A "System Process - Lost Delayed Write Error" error message implies that Microsoft Access had a problem writing data from its buffers to secondary storage. This can occur if the connection to a Network share stops functioning correctly. An "Invalid bookmark" error message will also occur numerous times for each field on each record in the current table or query that you are viewing if the share on which your data is stored becomes unavailable.


The following suggestions may help you to diagnose the problem:
