I have earlier SQL 2005 Express Edition install..I remove it from control panel.But its not completely remove,can somebody tell me how to completely remove it. Cz now I m using SQL Server 2000 ,even if i craete the user & connect to DB using SQL server authentication,I m still getting the same error..My frnd told me to completely uinstall SQL 2005 might solve this errror!!!!!

Can somebody tell y i m getting the same error even if I connect using SQL authentication???? Is the reason same told by mine frnd!!!

Tell me one thing more ,Suppose while creating a user , Suppose i give username A & default databse is sonia..& there is also other user named B whose default DB is sardana.
