We have used Crystal Report Web Viewer on ASP pages (using ActiveX), and it works perfectly on Windows 2000 machine with IIS 5 and SQL 2K. Now we already migrated the applications to Windows Server 2003 running IIS6, and still SQL2K. All the application works perfectly, except for the Crystal Report. Everytime the report in ActiveX shown blank, only the toolbar the frame shown, which means that the ActiveX is loaded but the report cannot be shown. I check through the Windows Event Viewer: there're warnings said: A process serving application pool 'DefaultAppPool' suffered a fatal communication error with the World Wide Web Publishing Service. The process id was '3580'. The data field contains the error number. (the number is 0000: 8007006d). A process serving application pool 'DefaultAppPool' terminated unexpectedly. The process id was '4708'. The process exit code was '0x80'. Check through log file in C:\Windows\System32\Log Files\httperr log file: Date/Time IP 80 HTTP/1.1 POST URL Connection_Abandoned_By_AppPool DefaultAppPool I have try to create new app pool, and grant to Network Service or even Local System, but the report still shown blank. Anyone has idea/ experience? Please help.
