Connecting to SQL2000 DB from SQL2008 Linked Server

Hi im trying to Access one Table of SQL 2000 from SQL 2008

for that i have created Linked Server in SQL 2008,

It is showing all the  Catalaogs also,but when im trying to access using the Query it is throwing error.

while configuring i choosed SQL SERVER OPTION Instead of Other Datasoure option.

select top 3 * from [Server].Database.dbo.myTable

and when i manually connect to SQL2000 by providing Credentials im able to access the data.

OLE DB provider "SQLNCLI10" for linked server "xxxxx" returned message "Unspecified error".
OLE DB provider "SQLNCLI10" for linked server "xxxxx" returned message "The stored procedure required to complete this operation

could not be found on the server. Please contact your system administrator."
