I have a reports website that serves up Crystal Reports via our SharePoint intranet site. Just now, we have started receiving the above error on all the Crystal Reports pages followed by:

private void SetDBLogonForReport(ConnectionInfo connectionInfo)
Line 79:     {
==>>Line 80:         TableLogOnInfos tableLogOnInfos = crystalReportViewer.LogOnInfo;
Line 81:         foreach (TableLogOnInfo tableLogOnInfo in tableLogOnInfos)
Line 82:         {

These pages have been working correctly for months and as far as I know nothing has changed on the reports nor on the server itself. What do I need to be checking to see what is causing this error all of a sudden?

Check the permissions on all the report files.  Also ensure no report files have be accidentally deleted.

What version of Crystal and Visual Studio?

Nothing has changed on the permissions side and all the reports are still physically there. I'm using VS 2010 with the SAP Crystal Reports add in. We have the path defined in a constants file as:

        public static string ReportsFolder = "\\\\sdwinerp01\\d$\\Ross\\Soft\\ERPWebComponents\\CrystalPDFViewer\\reports\\";

And that path works perfectly. It's happening on ALL the Crystal Reports now.

DId you check the permissions?
According to the SAP/Crystal site the cause is changed permissions or corrupted report files.

How did you publish the reports to the website?  According to SAP/Crystal
"If the Reports are published using visual studio ‘Publish’ option but if not published properly there is a possibility that the reports may lose content or get corrupted. "

Compare the report files to the DEV environment.

Can you copy one of the report files to a development machine and open it in Crystal?

GRrrrrrrr. We found the issue and have resolved the problem. The reports are located on a different server. We were having other issues on that server also and discovered there was an IP address conflict on that server with an access point someone had hooked up to a pc to configure. Once that access point was removed and the pc got its DHCP IP address back, the server was completely happy once again and reports are running as they should.
