Strange FileNotFoundException occuring on production server in console application

Question

Hi I have an application that works fine in my dev enviroment, but throws weird errors in the production enviroment, I checked the version of .net on my dev machine aswell as the production server , they both run 3.5.30729.01.

The exception I get is a System.IO.FileNotFoundException.

StackTrace:

Yesterday the error just went away, and today the error is occuring again. I tried using reflector on System.DirectoryServices.DirectorySearcher.FindOne() following the calls and it appears to have something to do with config files or user config files as you can see from the stacktrace

any ideas as to what config file it is trying to find and why it can't find them?

Answer 1

Use Process Monitor (or enhance you logging) to identify which file is not being found.

Answer 2

I would go with sysinternal "FileMon".

It's an application that catches every IO attempt, succesful or not. With pacience, you will see the name of the file not found.
