SYMPTOMS
When you try to perform an UPDATE operation or a DELETE operation against a remote OLE DB provider in Microsoft SQL Server 2000, a deadlock condition may occur. The deadlock condition may occur when the following conditions are true:
 * The remote OLE DB provider is configured as a linked server that has the Index as Access Path option set.

Note When the Index as Access Path option is set, SQL Server uses the IRowsetIndex OLE DB interface to select the requested records.
 * The remote OLE DB provider does not support the ICommand::Execute method.
 * The remote OLE DB provider only supports the IRowsetIndex interface and the IRowsetLocate interface.
 * The isolation level is set to REPEATABLE READ or to a higher isolation level.

Note This problem does not occur if the isolation level is set to READ COMMITTED or to a lower isolation level.

CAUSE
This problem occurs when you perform an UPDATE operation or a DELETE operation, and SQL Server creates multiple sessions to the remote OLE DB provider to perform the operation. For example, when you run the following query, multiple sessions are created to perform the DELETE operation. DELETE FROM  is the table name, and   is the column name that is key to an index.

When you run this query, SQL Server creates a session to locate the record. SQL Server then creates another session to delete the record. The first session passes the bookmark that was obtained in the first session to the second session to perform the DELETE operation. Therefore, a deadlock condition is created between the two sessions.
