trying to add recaptcha to an existing asp.net c# website
I have an existing website for a client which uses asp.net c# mainly due to logic for a side menu that was probably made from a template. Recently they experienced unwanted spam from their online form and so we found a solution in google's recaptcha to add in order to further prevent this, so now I have the task to make it work as desired.
I followed the instructions as diligently at http://code.google.com/apis/recaptcha/docs/aspnet.html and got my source code to work within visual studio on my local workstation and got this example so it had no errors nor warning messages at least. Great, I have helloworldc.aspx (see attached text file though keys are masked for security) and Bin/recaptcha.dll which I thought I could just upload to my web server via ftp, but now when I try to use the same code over on http://www.bhhlegal.com/helloworldc.aspx it blows some error messages that I don't quite get it.
While I understand in visual studio, just like doing a c#, that I need to add references to necessary dll files such as recaptcha.dll, but I'm lost as to where or what I have to do in my web server's IIS or web.config or something just to make recaptcha.dll available for our intended purposes.
Please advise so I can at least get this done, thanks.

Can you post up the actual web.config (obviously with connection strings removed), or at least the System.Web section please?
ASKER
Currently, the web.config file only contains the following for debugging purposes:
<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>
there's a library.cs file which basically works off a designed template for side menu purposes.

by updating the web.config file, I now get the following screen message when I click on my page:
Server Error
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.
The IIS log file shows as
2012-03-14 15:44:32 192.168.10.34 GET /helloworldc.aspx - 80 - 192.168.10.157 Mozilla/5.0+(compatible;+M SIE+9.0;+W indows+NT+ 6.1;+WOW64 ;+Trident/ 5.0) 500 23 50 187
I had tried restarting the IIS for that site and still got same thing.

Do you have access to the event log on the server? If so it may contain more detail on what the actual error is
ASKER
Yes I do, am not sure where under Event Viewer (Local) or elsewhere I should be looking at in particular.
I also ran my wireshark utility and saw a few lines that said the following when I click again onto my helloworldc page:
HTTP 416 GET /helloworldc.aspx HTTP/1.1
HTTP 1434 HTTP/1.1 500 Internal Server Error (text/html)

It'll be the Application event log you will need to look in, and you'll be looking for error events (with the red cross) at the right time - as you can reliably reproduce the issue its usually worth triggering it so there are entries at/near the top of the list, which is in descending chronological order.
I can't remember off the top of my head whether the events show as coming from IIS or asp.net (I think its the latter).

Hmmm, interesting, I just tried my helloworldc.aspx link from home and remotely to my office workstation and it now works. am perplexed as to why I got the error 500 at first but now it works. Hopefully I can add this to the form tomorrow successfully.
ASKER
Not sure why it now works, but it works at least. Hopefully it will work again tomorrow when I return to the office to proceed with the real form.

also I just found out the following from my peer:
I changed the application pool for bhhlegal from “integrated” to “classic”. It seems works now.
I read online that coldfusion8 changes a mapping that causes integrated mode not to work.
Not sure if you changed anything with asp.net or the web.config.
