Error connecting to database from Crystal Report

Question

Hi,
I am using Crystal report 2008, .NET 3.5 on Windows Server 2008 + SQL Server 2008
I have a batch that generates report (via export) then this batch will send the exported report via email.
I am encountering this error when reading report from BO Server
Error: CrystalDecisions.CrystalReports.Engine.LogOnException: Database logon failed. ---> System.Runtime.InteropServices.COMException (0x8004100F): Database logon failed.
   at CrystalDecisions.ReportAppServer.Controllers.ReportSourceClass.Export(ExportOptions pExportOptions, RequestContext pRequestContext)
   at CrystalDecisions.ReportSource.EromReportSourceBase.ExportToStream(ExportRequestContext reqContext)
While when trying to read the report from physical file within the server, it will give me this error
Error: CrystalDecisions.CrystalReports.Engine.InternalException: Failed to retrieve data from the database.
Details:  [Database Vendor Code: 2812 ]
Failed to retrieve data from the database.
Error in File IAREPORT {92DFCAFC-58AC-4CB3-B9DD-A9565E07088D}.rpt:

   at CrystalDecisions.ReportSource.EromReportSourceBase.ExportToStream(ExportRequestContext reqContext)
The report is working in our SIT environment but it is not working in our UAT environment.
I have tried the following:
1) running the batch (that generates the report) in SIT environment to call SIT database
Working fine
2) running the batch (that generates the report) in SIT environment to call UAT database
Will give the above error
3) running the batch (that generates the report) in UAT environment to call UAT database
Will give the above error
4) running the batch (that generates the report) in UAT environment to call SIT database
Working fine
For reading report from BO Server, I have tried viewing the report directly and scheduling the report directly from BO Server and it works fine.
Also I have tried to 'verify database' on the UAT report, but it seems it didn't solve the issue.
Does anyone have any idea how to solve this? Or what could cause this?
Appreciate your help.
Thanks.

Here's how I connect to the database
when reading report from bo server:
Dim enterpriseSession As CrystalDecisions.Enterprise.EnterpriseSession
            Dim enterpriseService As CrystalDecisions.Enterprise.EnterpriseService
            Dim infoObjects As CrystalDecisions.Enterprise.InfoObjects
            Dim infoObject As CrystalDecisions.Enterprise.InfoObject
            Dim infoStore As CrystalDecisions.Enterprise.InfoStore
            Dim query As String = ""
            query = "SELECT * FROM CI_INFOOBJECTS WHERE SI_PROGID = 'CrystalEnterprise.Report' AND SI_NAME LIKE '" & reportName & "'"
            'Create a session manager
            Dim sessionMgr As New CrystalDecisions.Enterprise.SessionMgr
            'Log into BusinessObjects Enterprise
            enterpriseSession = sessionMgr.Logon(cu.BOXIUser, cu.BOXIPwd, cu.BOXIServer, cu.BOXIAuthentication)
            'Create the infostore object
            enterpriseService = enterpriseSession.GetService("InfoStore")
            infoStore = New CrystalDecisions.Enterprise.InfoStore(enterpriseService)
            infoObjects = infoStore.Query(query)
            If (infoObjects.Count > 0) Then
                infoObject = infoObjects(1)
                crDoc.Load(infoObject, enterpriseSession)
                crDoc.SetParameterValue("@batchID", batchID)
                Dim CrExportOptions As ExportOptions
                Dim CrDiskFileDestinationOptions As New DiskFileDestinationOptions()
                Dim CrPDFFormatOptions As New PdfRtfWordFormatOptions
                Dim CrExcelFormatOptions As New ExcelFormatOptions
                CrDiskFileDestinationOptions.DiskFileName = reportFile
                CrExportOptions = crDoc.ExportOptions
                With CrExportOptions
                    .ExportDestinationType = ExportDestinationType.DiskFile
                    .ExportFormatType = IIf(reportFormat = IAConstant.PDF, _
                                            ExportFormatType.PortableDocFormat, _
                                            IIf(FINRptFormat = IAConstant.EXCELONLY, _
                                            ExportFormatType.ExcelRecord, ExportFormatType.Excel))
                    .DestinationOptions = CrDiskFileDestinationOptions
                    .FormatOptions = IIf(reportFormat = IAConstant.PDF, _
                                         CrPDFFormatOptions, CrExcelFormatOptions)
                End With
                crDoc.Export()
            Else
                Throw New ApplicationException(Constant.APP_ERR & " - Report not found")
            End If
The error is thrown when trying to export --> crDoc.Export()
The username and password are correct because it is the same username and password that the batch used to extract the data in the initial stage.
Here's how my batch works:
1) Extract and massage data directly from .net SP (this is working fine)
2) Obtain the report then use the same connection string (for physical path report) or use the report connection string (for bo server report), this report is using Stored Procedure (the problem starts here)
For reading report from bo server, I have also checked that the connection from the report itself is correct, because we can schedule/view the report from bo server successfully.
SQL Driver, is it the SQL Native Client you are saying? It's SQL Native Client 10.
I think we are using Business Objects Enterprise XI 3.1 Client Tools SP2 in our apps server.
