Try to set Data Source= "serverName" in you connectionString

Data Source=.\SQLEXPRESS will work only on local m/c, It will not work if you host your site

Check in web.config for connectionString, configure it according to your server name, password etc.

In Time Tracking System, it uses inbuild Membership classes for user creation, updation etc..

You have to register your DB with ASP.NET Membership classes by executing the command line utility in VS prompt

aspnet_regsql, it will open one window, where you  have to configure DB.

Hope it will help you, let me know.
