Can a sql server 2005 connect to a sql 2000 server?

However, you can use the SQL 2005 version of SQL Server Management Studio (SSMS) to connect to SQL 2000 servers and it works great.
In this manner,
Linked Server from SQL Server 2012 to SQL 2000 is not supported natively or directly. SQL Server 2012 comes with new version on native client i.e. SQLNCLI11, which only connect back to SQL 2008R2/2008/2005 versions. Also even if you install previous native client i.e. SQLNCLI10, it won't work.
In addition, Under SQL Server connection, select Use Windows Authentication to enable SQL Server Agent to connect to an instance of the SQL Server Database Engine with Microsoft Windows Authentication. Connections to SQL Server 2005 (9.x) and later databases require Windows Authentication.
Similarly,
Check if you are able to connect to SQL server by using a UDL file. If it works, then there may be an issue with the connection string. For instructions on the procedure about UDL test, move to Connect to SQL server by using a UDL file section. Check if you are able to connect to SQL Server from other client systems and different user logins.
Thereof,
You can upgrade your SQL Server 2000 instance to SQL Server 2008 R1 and then perform a subsequent upgrade to SQL Server 2008 R2. For an "in-situ" upgrade (MSDN links): You can upgrade instances of SQL Server 2000, SQL Server 2005 or SQL Server 2008 to SQL Server 2008 R2.
