I hope that's not your real sa password that you've just posted to a public forum!

Contact your DBA and get them to change the sa password IMMEDIATELY. You should also get them to check that the server is locked down and SQL is not available across the Internet.

Also, your application shouldn't be connecting as sa; use a specific user with only the permissions required for your application to run.

Solution 1

Make sure your Instance Name, User Name and password is connect. I would suggest to connect remote instance using Management studio and if it works then try these credentials in your project.

Please read this:

This page gives lots of examples how to build a proper connection string.

Your connection string does not make any sense.

Use a connection class like-

C#

public SqlConnection dbConnect()
    {
        cnnStr = "Data Source = 10.168.2.32";
        cnnStr += "; Initial Catalog = DBNAME";
        cnnStr += "; Integrated Security = false";
        cnnStr += "; User ID = userid";
        cnnStr += "; Password = password";

        return new SqlConnection(cnnStr);
    }
