Unable to load file or assembly *.dll

I have recently checked out and dusted off an older project from source safe. I do not know who originally created the .net project -- but i am starting to think that it was created in vs 2003.

I have vs 2008.

When i deploy the site to my dev IIS [local machine] and render it in a web browser i get the following error message:

Parser Error Message: Could not load file or assembly 'FSPI.Security' or one of its dependencies. The system cannot find the file specified. (C:\WIP\PartnerWeb\Partner\Partner\web.config line 41)

Source Error:

Line 39:       <system.web>
Line 40:             <httpModules>
Line 41:                   <add name="FSPIAuthenticationModule" type="FSPI.Security.AuthenticationModule,FSPI.Security"/>
Line 42:             </httpModules>
Line 43:             <trace enabled="false" pageOutput="true" localOnly="false" requestLimit="150"/>

Source File: C:\WIP\PartnerWeb\Partner\Partner\web.config    Line: 41

The dll being referenced appears to be custom written. I am really not sure what to do here?
Do I need to register the dll somehow?
Is the DLL referencing something from VS2003?

I have .net frameworks installed on my local iis dev machine for 1.1, 2.0, 3.0, and 3.5.

I have access to the dll via the Object Browser in VS2008 so I can relay any information needed so as to assist me with my trouble shooting -- I have done some 'googling' but I need some expert help on this one.

Let me know if anyone has any suggestions.

This is not dll
There will be .vb file in your app_code folder with the name FSPIAuthenticationModule.vb

this  might be custom httpmodule added for security purpose.

Thanks - I will look into it.

This was an error which occurred because I was unable to BUILD the project in VS2008. Once I took care of another error in the BUILD process and was able to BUILD the project, this error no longer appeared.

I don't know why I repeatedly capitalized BUILD in the above sentence.

Although this did not seem to be the cause of the error the information posted was still helpful.
