I had this issue with a specific application and not the entire IIS site  In my case  access to the application directory was not the problem  Instead  I needed to give the application pool a recycle    I think this was related to how the application was deployed and the IIS settings were set  done via scripts and a deployment agent

Changing pool from ASP NET v4 0 to Framework4 worked for me

User · Answer

I Think this is because of  IIS is unable to find the root folder  i e wwwroot  Restarting the IIS wont be helpful in some scenarios  if the root path has changed  you should bring it back to  SystemDrive  inetpub wwwroot  by right clicking sites node in IIS and changing physical path to the above one   and make sure that your application pool is asp net v4 0 and  running in integrated mode
