I have some reports that are served via a website (using CrystalReportViewer/CrystalReportSource). Up until a few days ago, things were working well (and have been for several months).
Suddenly I'm getting reports from users who are experiencing timeout issues on some (but not all) the reports. There have been no changes to the reports nor (as far as I know) the web server box nor database.
Checking the reports via the browser does show that they are, indeed, showing timeout errors. Checking the reports through the Crystal Reports XI app on the web server box displays the error "Failed to open the connection"
Checking the report locally (on my machine where the reports were initially developed) and everything runs fine. Loading the data takes about two or three seconds.
Copying the working report from my box to the web server box and running it within the Crystal Reports XI app there and it fails as above.
Any ideas? What should I be looking for?
TIA
