IIS Crash Export to PDF



Recently our application (ASP.NET running on IIS6 / Windows 2003 Std Edition) crashed, and we found the following error in the Windows Event Log:

Event Type: Information

Event Source: Application Popup

Event Category: None

Event ID: 26


Application popup: {BCDB6DD6-88D6-4196-A1E6-9E920777B515}: w3wp.exe - Unable To Locate Component : This application has failed to start because cxlib-4-0.dll was not found. Re-installing the application may fix this problem.

We had to restart IIS for our application to start working again at all.

The DLL in question belongs to Crystal Reports, we use it to generate PDFs on the fly on the web server from Reports. This component is normally working, and is present in its usual location. Why might we have seen this error, and why would the W3WP IIS process be temporarily unable to locate the DLL?

The problem has happen 4 or 5 times in past few months. It brings down the Application Pool and need to complete an IISRESET to the application to work again...

Help please....!
