从SQL Server 2008 R2更改为SQL Server 2014后不再运行报告

Question

Our crystal reports no longer run after changing the back end database from SQL Server 2008 R2 to SQL Server 2014 (both were enterprise). The database was backed-up on 2008 and restored on 2014 using SQL Server Management Studio. The .Net application works fine except for none of the Crystal Reports run. The screen simply flashes and no PDF is generated or delivered. Reports work fine if we change the connection string in the web.config back to the original server and DB. Below is the connection string with SERVERNAME, DBNAME, USER and Password changed to protect the innocent. The only thing that gets changed is the SERVERNAME.

<add name="Pubs" 
     connectionString="Data Source=SERVERNAME;Initial Catalog=DBNAME;Integrated Security=False;User Id=USER;Password=*********" 
     providerName="System.Data.SqlClient" />

Thank you.

UPDATE:

After checking again, I'm now seeing authentication failures in the SQL logs. I'm not completely sure if these are coming from Crystal Reports. The client IP an a completely different IIS web site IP on the same web server that shouldn't be talking to this DB.

Login failed for user '******'. Reason: Password did not match that for the login provided. [CLIENT: x.x.x.x]
Source Logon
Message
Error: 18456, Severity: 14, State: 8.

UPDATE #2

The developer apparently found some issues with the reports lacking a port being specified for connection and is going through the reports resolving the issue.

Thanks for the input.

Answer 1

The developer apparently found some issues with the reports lacking a port being specified for connection when calling the report from code. They are going through the reports and making the updates to resolve the issue.

Developer input follows....

Had to change subreport logon:

rpt.SetDatabaseLogon(sConn.UserID, sConn.Password, sConn.DataSource + ",1433", sConn.InitialCatalog);
            foreach (ReportDocument subReport in rpt.Subreports)
            {
                subReport.SetDatabaseLogon(sConn.UserID, sConn.Password, sConn.DataSource + ",1433", sConn.InitialCatalog);
                for (int i = 0; i < subReport.DataSourceConnections.Count; i++)
                {
                    subReport.DataSourceConnections[i].SetConnection(sConn.DataSource + ",1433", sConn.InitialCatalog, sConn.UserID, sConn.Password);
                    subReport.DataSourceConnections[i].IntegratedSecurity = false;
                }
            }
            for (int i = 0; i < rpt.DataSourceConnections.Count; i++)
            {
                rpt.DataSourceConnections[i].SetConnection(sConn.DataSource + ",1433", sConn.InitialCatalog, sConn.UserID, sConn.Password);
                rpt.DataSourceConnections[i].IntegratedSecurity = false;
            }

To this:

foreach (IConnectionInfo conn in rpt.DataSourceConnections)
        {
            conn.SetLogon(sConn.UserID, sConn.Password);
            conn.SetConnection(sConn.DataSource + ",1433", sConn.InitialCatalog, false);
        }

        rpt.SetDatabaseLogon(sConn.UserID, sConn.Password);

        foreach (Table t in rpt.Database.Tables)
        {
            t.LogOnInfo.ConnectionInfo.UserID = sConn.UserID;
            t.LogOnInfo.ConnectionInfo.Password = sConn.Password;
        }
