Error linked server query after installing SP4 on SQL 2000

Hello
SQL 2000 SP3a run fine with an linked server query like
select * from openquery( linkedOlapServer, .. here is the MDX ...')
After installing SP4 build 2039 this query fails with error:
Server: Msg 7302, Level 16, State 1, Line 1
Could not create an instance of OLE DB provider 'MSOLAP'.
OLE DB error trace [Non-interface error: CoCreate of DSO for MSOLAP
returned 0x80040154].
Appreciate hints from experience on which hot fix do I need to install?
Nic
Does changing the "AllowInProcess" to something non zero fix this problem?

In Object Explorer, right-click the provider name and select Properties. The
following table describes the available provider options...
thanks,
