My first task is create a very basic team site with a URL www.sowmyan.com 1. First I am going to enter a host entry in the DNS in my Domain Controller(you can do it even after creating the site, but here I am going to add a new host entry with name “www”, thus the FQDN will be www.sowmyan.com ) and pointing it to the IP address of my SharePoint server. 2. Now create a new web application in SharePoint central administration site. While creating the web application specify the port as 80 and host header as www.sowmyan.com , so while accessing the URL it will be neat and no need to specify port number. 3. After creating the web application creating a new site collection at the root. 4. Once the site got created browse to the site and if there is a loop back check then we can’t successfully login to the site, it may prompt for credentials 3 times and will show blank page. To resolve this
