When executing an Impromptu query against SQL Server 2000 SP3a, errors are encountered relating to Intra-query Parallelism causing deadlocks. Following the suggestions in KB118635 (changing the processing to flexible) does not resolve the situation.
DMS-E-GENERAL, A general exception has occurred during operation 'asynchronous open'.
DMS-E-RDS_OLEDB, The OLE DB provider has returned the following error:
HRESULT: E_FAIL
Microsoft OLE DB Provider for SQL Server
Intra-query parallelism caused your server command (process ID #58) to deadlock. Rerun the query without intra-query parallelism by using the query hint option (maxdop 1).
SQLSTATE = 42000, ERROR = 8650
