Server Error in '/' Application

Hello Experts,
I converted a web project from vs 2003 to vs 2010.  It is running fine in my local machine.  But when I deployed it in our web server with Windows 2008 OS, I am getting the below error.  Please see the attachment.  I am using the right Framework 4.0 in web.config file.  Also, in IIS, I did the necessary changes.  Do you have any idea?  Thank you in advance.

That message is telling you what to do to be able to view the error.

Try accessing the site from the server itself, you should get a more descriptive error.

Can you upload a screenshot of the one ran from the server not a client.
RadhaKrishnaKiJayaAuthor Commented:
It is exact same Runtime Error.
MikeNetwork & Systems ManagerCommented:
That's odd, it should be different as the one above suggests that remote errors are disabled. Are all the required application pools started and set to use the new version? It's kind of hard to diagnose without an actual error though.

You need to make the change suggested in that message before you can see the actual error message.

^ This is why I am confused you are getting the same message as the screenshot suggests browsing the site from the local server to see the message.

I think the default 'mode' does not display any errors.  This is what I had to put in my 'web.config' to show errors in the browser.  I would imagine that a .NET application will have more in that file.
<?xml version="1.0"?>
        <httpErrors errorMode="Detailed" />
        <asp scriptErrorSentToBrowser="true"/>
        <urlCompression doDynamicCompression="true" doStaticCompression="true"/> 
        <customErrors mode="Off"/>
        <compilation debug="true"/>

I did the change as suggested and getting "An operations error occurred" message.  Do you think it is related to security issue?

Thank you for your time.
RadhaKrishnaKiJayaAuthor Commented:
I changed a new application pool with Integrated mode and applied that to the Basic Settings.  It is working now.  Thank you guys for your quick response.   I have no words.
