Have you ever wondered how you could deny access for users on a Sharepoint 2010 site. I had a need i wanted to make a site not to be accessible for the users, luckly I had the root site configured on a site-collection level.  In SharePoint 2010 there is a setting where you can make users on a site Collection from adding any content, making it Read-Only or Denying Access.

Step 1.
Navigate to Central Admin >Application Management > Configure Quotas and Locks

Step 2.
Select the Site Collection you want to Lock,  appropriate Option you like. Here you can select to make it "Read-Only" "No Access" or prevent users from adding content

Step 3.

Type in "Additional Lock Information

Step 4.
Click OK

Now when the users try to access the site, they will be forbidden.
