Had to move Internal website from one server to another and I get different results on new server

I have an internal web site running on a new server.    I have installed all the same roles/services on the new service, yet when I try to bring up the starting page I get this message.
___________________________________________________________________
http://localhost:/login.asp
____________________________________________________________________
The website cannot display the page
 
  HTTP 500
 
   
Most likely causes:
•The website is under maintenance.
•The website has a programming error.
 
   
What you can try:
 
   

  Retype the address.  
 
   

  Go back to the previous page.  
 
   
I have looked at all the installed services and they match the old server.    They are both running IIS7 and they both have the same Website name      SalesmanwebAccess     but I get different results.    On the old server the Login.asp page comes up.    Any suggestions on where to start looking.    I thought I had matched the permissions for the folder.
