getting a "path not found" error with this line rcd.PrintOutputController.Export(CrReportExportFormatEnum.crReportExportFormatPDF)

I have two test servers.  Both are running Windows 2012 with Crystal Reports 2012.

On the first server (which is working nicely), I has an ASP.net application which include Crystal Reports.  All the files for the IIS server are on the local D:\ drive.

On the second server, I copied the first server, and then moved the IIS files to a network share, and then configured IIS to use the network share.  I then took the Crystal Reports part of the application and put it back on the D:\ local drive.

Now in this code (same code on both servers), I have the following

             myBytes = New CrystalDecisions.ReportAppServer.CommonObjectModel.ByteArray

             myBytes = rcd.PrintOutputController.Export(CrReportExportFormatEnum.crReportExportFormatPDF)

On the first server, this works great,

On the second server, I get the following error message.

   at CrystalDecisions.ReportAppServer.Controllers.PrintOutputControllerClass.Export(CrReportExportFormatEnum exportFormat, Int32 Reserved)

   at clsCR2008.buildPDF(String expDir, String reportPath, String strServer, String strDatabase, String strUser, String strPassword, String strUserID)

Any suggestions on how to fix this problem?
