Do you have error handling in place? If yes, the best solution would be to check out the logs for error details.
And if you don't, the first place to check is the event log. If you don't find much details there you may check IIS logs and HttpErr log file (IIS 6+). IIS 7 also has failed request tracing for better analysis.
All these methods require access to server on which your code is hosted. But that's the only option if you do not have a good exception handling in your project.

Hope that helps!
