To clarify: when you run from SP3 to SP4 it works, but when you run
from SP4 to SP3 it fails? Since the remote server is not doing anything
here; the error comes from OLE DB provider, SP4 is a but suspect here.
(But SP3 -> SP4 could work because SQL Server chooses another query plan.)

If you need this to work, I would suggest that you try to set up a linked
server with the MSDASQL provider. MSDASQL is OLE DB over ODBC, and usually
inferior, but sometimes it performs things differently than SQLOLEDB.
Look in Books Online under sp_addlinkedserver for an example of setting
up a linked server with MSDASQL.
