SQL 2005 64bit with Linked Server SQL 2000 Query Issues

We just upgrade our main DB from SQL 2k to SQL 2k5 64bit. But we still need to use linked server to link to another SQL 2k for running some queries. But I get the following error when trying to execute some query:

OLE DB provider "SQLNCLI" for linked server "SQL 2k Server" returned message "Communication link failure".
Msg 10054, Level 16, State 1, Line 0TCP Provider: An existing connection was forcibly closed by the remote host.Msg 18456, Level 14, State 1, Line 0

The solution is: When running a query, SQL 2k5 64bit is trying to invoke the sp_tables_info_rowset_64 store procedure. But this proc is not in SQL 2k server. So one wrapper is needed to put in SQL 2k server to make the query work.

Create Procedure sp_tables_info_rowset_64
@table_name sysname,
@table_schema sysname = null,
@table_type nvarchar(255) = null
as
declare @Result int
set @Result = 0
exec @Result = sp_tables_info_rowset @table_name, @table_schema, @table_type
