Problem configuring the MS SQL Server Intelligent adapter

I’m getting the following error, while configuring the MS SQL server enterprise adapter(intelligent).
Could not find the database. Connect() failed.

(DB = MSSQL Server 2000)
(Drivers = Microsoft type IV jdbc drivers)
(platform = Windows 2000)

The DB is on the same server. I don’t have much experience with MSSQL server. On the SQL Server tab, what do i need to specify in the SQL server parameter: just the DB name or the DB URL.
Anything else I might be overlooking.
