ASP.NET website shows 503 Service Unavailable after successful publishing

asp.net web publishing http-status-code-503

Every time I try to publish a website, it runs fine but when the website opens up it gives me a,

"HTTP Error 503. The service is unavailable."

Everywhere I look on the internet talks about it being my application pool but that seems to be running fine. I think it may be my web.config file but I'm not entirely sure.

PLEASE can someone help me.

Make absolute sure the App Pool is running

Goto WinKey+R (Start > Run) type in InetMgr, press enter. Left side, Connections, expand your computer or the server in question. Select Application pools. Start all pools that have their "Status" as Stopped.

Make sure the site is set to the correct pool

Not all sites are assigned to the default application pool, in this case, in the left side expand sites, find your site, expand it. In the right column, click Basic configurations. Edit the application pool there, go back to the first block and make sure your newly assigned Application Pool is running.

Test it

Select your site again, In the right side, there is a Browse site group, click on Browse *:80 (or something like that, this should do it).

Check permissions on site's folder.

Go to your site folder and give full permission to NETWORK SERVICE.

Make sure Application Pool service is not disabled in windows services.

If everything else fails, go to Services.msc and set the service related to your app pool to Automatic (maybe you or someone disabled it for some reason, who knows).

Reinstall IIS

Go to Control panel > Programs and resources > Install Windows Resources, find everything related to .NET, ASP.NET and install. Check all leftover boxes from IIS and subselects. If this fails, uninstall it completely then install it again.

Let us know if any of these work.
