Regarding VS Web part Solution Deployment Permission in SharePoint Server other than Admin

Hi,

While deploying the Visual Studio Web part, one error occurred i;e,   “Error occurred in deployment step 'Recycle IIS Application Pool': The local SharePoint server is not available. Check that the server is running and connected to the SharePoint farm.”

Actually we want that two user can deploy their web part simultaneously. One is admin that is able to deploy web part. But another user is facing this problem.

Solution which we have tried:

1. Make Local admin to that user.
2. Assign db_owner permission to that user in database.
3. Add that user in WSS_Admin_WPG group.
4. Add in Farm administrator group.

But still we are facing the same issue
