HELP !! Running SQL 2000 using ADO command object from Access 2000

I'm running a SQL 2000 stored procedure from Access client using
SQLOLEDB provider and ADO Command object. The stored procedure only
returns a Return Value and no recordset.

When ran from Query Analyzer, it runs in less than 4 seconds. When ran
from Access client using objects noted above, it takes whopping 40
seconds and it times out!! Ran SQL profiler, but I cannot see anything
suspicious because it all occurrs within a stored procedure. Event
viewer of the server where the Access client is running from revealed
next to nothing. Is there a chance that overhead from ADO command
object is slowing the execution ?

If anyone could think of a reason why a same procedure will run much
slower within ADO command object, please help!!!!
