App.config path not correctly interpreted by ASP.NET Application

I'm working on a very old project (2000) in VB6 which was "modernized" and upgraded to VB.NET 3.5. I've centralized every old INI configuration file into one MainApp.config, which is referenced by the app.config of every component.

There's an VB ASP.NET website in the solution, which uses DLL components, which are looking into app.config for parameters like, say, error log directory, etc.

I've deployed the site on my dev. server (Windows 2008 Server w/ IIS 7.0) into the D:\WebSite开发者_运维知识库\ directory.

Problem: When running the site, an error occurs. A DLL is looking into app.config for the parameter RepertoireErreur which has the value .\Erreurs\

Instead of returning

D:\WebSite\Erreurs\

it returns

c:\windows\system32\inetsrv\.\Erreurs\

which doesn't contain the Erreurs directory. Boom. Error.

Does anyone have ever encountered the same problem ? Is there a solution ?

Thanks,

If the web.config contains a key with the value .\Erreurs\, then that is what it will return, i.e. the string ".\Erreurs\". Your problem probably lies with whatever you are doing with the parameter. The value you say it returns looks like the directory of the iis executable file with your value appended on. Please post code to show what your dll is doing with the value it retreives from the config. See this for how to determine the local physical path of the website.

Ok, That's weird: Everything is finally working. The DLL gets the correct path to write in. I don't get it, but it suddenly works. I guess I'll never know why ! :P Thanks for your help, everyone.
