SectionGroup is new to .NET 2.0.  Is the virtual directory you are using on the web server configured to use asp.net 2.0 in IIS?

Hi,
could you please explain this further...

Go to IIS Admin on the server.  Look for the virtual directory you are publishing to. Look as the Properties.  Under the ASP.NET tab, make sure it's set to 2.0.50727

yes i am using version 2.0 of .NET Framework... i.e 2.0.50727

What could be the problem?

It works seemlessly on my local machine.... but fails on the server

Every time I've seen this it's because the virtual dir on the server was set to .NET 1.1

dstanley9Commented:
The virutal dir it will use is the dir that web.config is in.  It also has to be set up as an application in IIS - if the dir is not set as an application the "Application Name" text box in IIS will be grayed out.

Yes,
I have set the Virtual Directory by clicking on the create button...

If the virtual directory was not created then it wouldnt go as far as the web.config file in the application...

it would simple give an /Application error

And the ASP.NET tab for that virtual dir shows version 2.0?

Can you run aspnet_regiis -lk on the server and post the results?  You can remove references to paths that are not part of your deployment.
