I am getting the following error in my client system while trying to connect the server :-Login failed for user ''.The user is not associated with a trusted sql server connection.
I am using sql server 2005 management studio express and c#.net.
Below is my connection string :-
public SqlConnection con = new SqlConnection(@"data source=IP of server\SQLEXPRESS;User Id=sa;Initial Catalog=dbsaiscan;Integrated Security=True;Persist Security Info=True;Trusted_Connection=Yes");
Any help wiill be highly appreciated.
