Linked Server Error

SQL 2000, Sp3a on Windows 2000. I have a linked server set up to an AS400
using MS OLE DB Provider for DB2, which comes with Host Integration Server.
I have just started to get an error on this LS when trying to use it,
although previously (before Sunday!) it worked fine:
ERROR 7303: Could not initialise data source object of OLE DB provider
'DB2OLEDB'
SqlDumpExceptionHandler: Process 54 generated fatal exception c000005
EXCEPTION ACCESS VIOLATION.SQL Server is terminating this process.
I have bounced the server and checked the event log but it gives me no
additional information. Logon credentials are OK for linked server and I can
ping the box. Nothing new has been installed on the server.
I've got a stack sump generated when the exception occurred if that's useful
to anyone...?
