Hello,
              
I have installed SharePoint 2013(Enterprise Edition) on my server .I have
followed whatever the steps given.Their is no installation problem at the time
of setup.Setup is completed very well.After that I have able to open SharePoint
Central admin also,Using central admin I have created new site but problem is
that,the new create site are not opening it gives error
but I am confusing because I am not understanding what is the actual problem
because,when opening new site it asks for UserName & Password ,I am giving
credentials but after processing it will gives error like (500 Internal server
Error)also 
I have checked the all IIS setting  It is working fine 
-The Application Pool is also created and it is started still the new site
is not opening.Please give me the solution regarding same
     Thanks,
