Compiler Error

[Guest]

In the latest version of our Web Application we have started seeing the following error message - "External component has thrown an exception", Stack Trace is shown below
Only minor bug fixes in the .vb codebehind files have been done between a previous version that was fine and this one
I have googled on this but not found any answer or suggestions as to where to start looking. Is this error in my code (.vb or .aspx) or a build option or deployment issue

The application is built and deployed to .Net Framework 1.0 and runs on Win2k SP4

Hi,

It's hard to know but your Stack Trace implies that something goes wrong
in the dynamic process of creating assembly that represent the page HTML
definition. What I suggest:

1) Delete the cache of your application from asp.net temporary files
directory located under C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322.

2) Double check with source safe for changes between the last deployed
version and the current one in the pages HTML.
