Unable to attach to process and debug web application

Hi Team,

I am running Visual Studio 2010 on windows server 2008 R2 enterprise and developing an web application in C#.Net.

I have set up the default website in localhost in IIS to run the website and it is not working.

PFA for Your ref....

Debug- attach to process

Select W3WP.exe in the Available Process section ( I have ticked Show processes  from all users and Show Processes in all sessioons if it is not there)

after that also unable to see that port which i have added it in IIS.

 187

1875 marked with blue colour is my local port address.

Regards

Anantha
