Go to browser, on error page check the section "Config Source"


you will find error in specific section.
for example my error was


<system.webServer>
 <handlers> 


do following as per your error 

1) first go to following location
    C:\Windows\System32\inetsrv\config
2) Open the application "applicationHost.config"


go to particular section in my case


<sectionGroup name="system.webServer">
  <section name="handlers" overrideModeDefault="Deny" />


Change overrideModeDefault="Allow"

3) Reset IIS
