Database logon failed

good day.

i am receiving a "database logon failed" error in the code below.  the code works on my development machine; however, it fails on the clients and i cannot figure out why.  the client machines run other crystal reports with similiar code below.

any help would be appreciated.

                if (_header.ID > 0)
                    ReportDocument rep = new ReportDocument();
                    rep.Load(System.Windows.Forms.Application.StartupPath + reportName);
                    TableLogOnInfo tliCurrent;
                    foreach (Table curr in rep.Database.Tables)
                        tliCurrent = curr.LogOnInfo;
                        tliCurrent.ConnectionInfo.ServerName = severName;
                        tliCurrent.ConnectionInfo.UserID = uID;
                        tliCurrent.ConnectionInfo.Password = uPWD;
                        tliCurrent.ConnectionInfo.DatabaseName = dbName;
                    ParameterValues pvCollection = new ParameterValues();
                    ParameterDiscreteValue rmaCounter = new ParameterDiscreteValue();
                    rmaCounter.Value = _header.ID;
                    rep.PrintOptions.PrinterDuplex = PrinterDuplex.Default;
                    rep.PrintOptions.PrinterName = Properties.Settings.Default.PrinterName.ToString();
                    rep.PrintToPrinter(1, true, 1, 999);
                    rep = null;
                else MessageBox.Show("Sorry, there is no current RMA record loaded.", "Data Required", MessageBoxButtons.OK);
            catch (Exception ex)
                LogWriter.LogWriter.WriteError("Error in printing RMA packing slip: " + ex.Message);

i also tried to replace the foreach loop with a SetDatabaseLogon() command; however, that didn't fix the problem either.
I assume the user has permissions and you are passing the correct password.

The code looks correct.

Does the report have a subreport?

freezingHotAuthor Commented:
yes, in fact, i even added the sa username/password just to make sure.

no, the report does not have a subreport.

Are you using the CR XI R2 runtimes with the application?

i believe so - i downloaded and installed the merge modules from SP2.  in addition, other reports are working fine.  there is only one (1) report that is failing with this error code.
Since this is the only one then the applicatiion is probably ok.

What is different about this report?

finally found it...

the database provider was set as SQL Server Native Client - the client machines may not have had the drivers.  Changed it to OLEDB for SQL Server and it worked... thanks for steering me in the right direction.

have a good one.
