"Recycle IIS Application Pool" error while deploying solution using Visual Studio

Hi All,

I am getting below error while deploying solution from Visual Studio. I have verified the URL and its okay and site is also up and running and accessible.

Error 1 Error occurred in deployment step 'Recycle IIS Application Pool': Cannot connect to the SharePoint site:http://portal/sites/site1/. Make sure that this is a valid URL and the SharePoint site is running on the local computer. If you moved this project to a new computer or if the URL of the SharePoint site has changed since you created the project, update the Site URL property of the project.

Suggest some solution.

Thanks in advance.
