and invalid username and password

An unhandled exception of type 'System.IO.IOException' occurred in mscorlib.dll

Additional information: username and password

Answer 1

Before connecting to the server you will need to impersonate the login using the username and password you have. The following stack overflow should help a bit with writing that code: How do you do Impersonation in .NET? .

A shortened version is:

    public Impersonation(string domain, string username, string password)
    {
        var ok = LogonUser(username, domain, password,
                       LOGON32_LOGON_NEW_CREDENTIALS, 0, out this._handle);
        if (!ok)
        {
            var errorCode = Marshal.GetLastWin32Error();
            throw new ApplicationException(string.Format("Could not impersonate the elevated user.  LogonUser returned error code {0}.", errorCode));
        }

        this._context = WindowsIdentity.Impersonate(this._handle.DangerousGetHandle());
    }

Good luck!
