IIS on Windows 10. Server Error 503

Question

I have Windows 10 and I want to run IIS. I have activeted all features for it, as you can see here. Then I type "localhost" in the browser and I take

"HTTP Error 503. The service is unavailable."

In some forums they say to control the log HTTP Error file, so I do, but it is empty.

Then I go to the ISS manager to see for configurations.

How can I resolve this "Il server è configurato per l'uso dell'autenticazione pass-through con un account predefinito per accedere al percorso fisico specificato. Tuttavia, Gestione IIS non può verificare se l'account predefinito ha l'accesso. Verificare che l'identità del pool di applicazioni abbia l'accesso in lettura al percorso fisico. Se questo server è aggiunto a un dominio e l'identità del pool di applicazioni è NetworkService o LocalSystem, verificare che '< dominio>\< nome_computer>$' abbia l'accesso in lettura al percorso fisico, quindi riprovare queste impostazioni."?

I understand that I have to verify if the identity of the App pool has the reading access to the physical path. Please help me. Thank you.

Answer 1

With IIS, the error message "HTTP Error 503. The service is unavailable." typically means the site itself is running but the application pool associated with the site is stopped. Check the application pool and start it if is stopped.

If you see the application pool stopping again after you request the page, check your Event Viewer for error entries explaining why it stopped the pool.

Answer 2

Just update the credentials in Application pool. You can update this by going to IIS manager=>Application Pools=> your pool name=>Right click then Advance Settings =>Identity=> custom and update the username and password that may help.
