    I have typically seen this when the underlying connection was closed in between getting the reader and using the reader. If you are using a global connection check that it didn’t get closed somewhere earlier.

    For example the following code block will receive the 5018 error on the “read” since the connection was already closed.

            AdsConnection cn = new AdsConnection("data source=c:\\");
        cn.Open();
        AdsCommand cmd = cn.CreateCommand();
        cmd.CommandText = "EXECUTE PROCEDURE sp_mgGetInstallInfo()";
        AdsDataReader dr = cmd.ExecuteReader();
        cn.Close();
        dr.Read();

    If you move the cn.Close(); to after the read you should not get the error.
