error 7390 when isolation level is set to serializable...

I am trying to replicate the execution of a stored procedure and hence am using isolation level of serializable as recommended by BOL for purge operations.
This following code works fine when executed on the server ( logging in via terminal services) bu gives me an error when executed thru Query Analyzer.
Really puzzled.
________________________________________________________
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE
GO
begin transaction
exec dbo.DeleteJobRunResults @.SourceSystem = 'GSP Risk Engine',
@.SourceSystemCode = '13397'
commit transaction
go
_________________________________________________________
***************************************************
Server: Msg 7390, Level 16, State 1, Line 1
The requested operation could not be performed because the OLE DB provider 'ADSDSOObject' does not support the required transaction interface.
OLE DB error trace [OLE/DB Provider 'ADSDSOObject' IUnknown::QueryInterface returned 0x80004002].
*****************************************************
Any help will be appreciated
thanks
-sriniHi srinivas,
Check the following registry key and make sure it is set to 1:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\ Providers\ADSDSOObject
Thanks,
