Crystal Reports: Database Logon Failed

Question

I have application in ASP.NET (C#) in which I use Sap Crystal Reports for Visual Studio. In VS everything works perfect. But when I deploy it to IIS \"Database Logon Failed\" er

Answer 1

We had similar issue/error message: CR worked fine on most PCs including production server but on one particular dev. PC it did not. We checked Database Sources drivers and "SQL Native Client" was missing while "SQL Server Client" and "SQL Server Native Client" were present. We installed version 2005 from here http://www.microsoft.com/en-us/download/details.aspx?id=11988 (for 64-bit OS) and it started working.
