hi, I have a very frustrating issue trying to set up a linked server from SQL 2005 to SQL 2000, with windows accountauthentication. TCP doesn't work at all, and read that named pipes could be used instead. Note: NP is enabled on both servers as well, and I set up an alias on the SQL2K box to the SQL2K box. Also, timeout on the linked server is set to 0<br /><br />I get the following errors when I attempt to run a query ie (select * from server.db.dbo.table): PLEASE HELP![<img src='/community/emoticons/emotion-6.gif' alt='' />]<br /><br />OLE DB provider "SQLNCLI" for linked server "JDEQADEV1" returned message "Login timeout expired".<br />OLE DB provider "SQLNCLI" for linked server "JDEQADEV1" returned message "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.".<br />Msg 5, Level 16, State 1, Line 0<br />Named Pipes Provider: Could not open a connection to SQL Server .
