IIS 7 Not Renedering Pages as Local

Hello Gurus,

I am new to IIS, We have the ASP.net Application which runs well on Local as well  with other Browers. But when we Deployed to IIS7 Test Server , we are seeing the following Issues

1) The Rounded Text Boxes does not show up as in Chrome, Firefox . They do show up correctly on Local  on All the browsers including IE.

2) Some of the Panel behave Differently , but they behave correctly when we open the Page on  Chrome and FireFox . On Local again no issues from all the 3 browsers

I have gone through  the forums and Checked Static Content on IIS, which is also installed  as well compatibility View Settiing, tried with both enable and disable , Modified the Config  file with 

<httpProtocol>    

<customHeaders>     

<clear />     

<add name="X-UA-Compatible" value="IE=EmulateIE8" />    

</customHeaders>  

 </httpProtocol>

Still No Luck  .

Any suggestions are greatly appreciated.

Thank you,

Mahi
