steps i Follow-
1) Go to Control panel-->Admintrative Tools-->Double -click
Data sources(ODBC)-->click Add button-->I choose SQL server
(last option), Is it right or wrong option for connecting 
to SQL 2000.Then a new screen appears Create a New 
dataSource-->in name textbox,we can write anyname--Right or 
wrong. suppose i enter sonia, & my server name is .,so I 
enter . in server & click next button-->On the Next screen 
i have checked the option With Sql server authentication--
>Login Id-sa, Password-->Blank-->Click next button-->Next--
>Finish-->Then I click on button Test Data source-->Mesage 
Comes TESTS COMPLETED SUCCESSFULLY-->OK-->OK-->Ok.
