I am using C# ASP.NET to publish crystal reports from oracle 10 g database. I am getting the following error in one of the reports

UNSUCCESSFULLSystem.Runtime.InteropServices.COMException (0x8004100F): Logon failed. Details: ADO Error Code: 0x Source: Microsoft OLE DB Provider for Oracle Description: ORA-01017: invalid username/password; logon denied Native Error: Error in File C:\DOCUME~1\NET_AD~1\LOCALS~1\Temp\1\ReportName {3DF1813B-DA04-43A8-89B1-8163580097F0}.rpt: Unable to connect: incorrect log on parameters. at CrystalDecisions.ReportAppServer.Controllers.ReportSourceClass.Export(ExportOptions pExportOptions, RequestContext pRequestContext) at CrystalDecisions.ReportSource.EromReportSourceBase.ExportToStream(ExportRequestContext reqContext)

The other reports are working fine. I need help with this urgently, please.
