You should try to remove IIS Express folder at %USERPROFILE%\Documents.

Next important thing is to restart Visual Studio and open it as admin.

Then you can right click your ASP.NET project and go into Properties view. There you can configure web settings for IIS hosting in the Web tab. Try to change IIS settings here and then save with Ctrl+S.

When there is a * next to the web tab because you tried to edit settings but could not save, you need to change to another tab, switch back to Web tab and then save with Ctrl+S. (The Properties view for ASP.NET apps in Visual Studio is still buggy ...)

I am currently using Visual Studio 2015 CE so I don't know whether my solution applies to your problem. Anyways try to remove any folders that got cached by IIS Express hosting and never really got cleaned up afterwards.

blocks|key|4519019|text|我用一个类似的解决方案遇到了类似的问题：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4519020|场景:我让应用程序池在一个用户帐户下运行，它的密码已经被更改，因为它已经过期了。我从来没有更新过IIS，所以每次尝试运行网站时，应用程序池都会自动停止。即使我手动启动AppPool，它也会在网站运行时停止。|4519021|解决方案:更新IIS上帐户的凭据或使用其他帐户|4519022|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

I had a similar problem with a similar solution:

Scenario: I had the app pool running under an user account and it's password had been changed because it had expired. I never updated IIS so the app pool would stop by itself every time when a try to run website. Even if I start AppPool manually, It stopped on website run. 

Solution: update the credentials for the account on IIS or use another account

blocks|key|4519039|text|最近在Windows10更新(Dev机器)后，我遇到了这个问题。我已经创建了一个新的IIS+AppPool，并分配到网站，解决了这个问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4519040|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I have faced this issue recently after Windows 10 update (Dev machine). 
I have created a new IIS AppPool and assigned to the website and that fixed the issue.

blocks|key|11482|text|因此，在我的例子中，唯一解决这个问题的方法是在一个新的绑定协议中静态地设置ip，在你的例子中应该是这样的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|11483|<site+name="SMApplication(4)"+id="10">
++++++<application+path="/"+applicationPool="Clr4IntegratedAppPool">
++++++<virtualDirectory+path="/"+physicalPath="C:\Users\DanZe3\Documents\Visual+Studio+2013\Projects\SMApplication\SMApplication"+/>
++++++</application>
++++++<bindings>
++++++<binding+protocol="http"+bindingInformation="*:29790:localhost"+/>
++++++<binding+protocol="http"+bindingInformation="*:29790:192.168.1.8"+/>
++++++</bindings>
+</site>|code-block|syntax|javascript|11484|这在生产环境中不会造成任何问题。|11485|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

So, in my case the only thing that fixed this was setting the ip statically in a new binding protocol, in your case would be something like this:

<pre><code>&lt;site name="SMApplication(4)" id="10"&gt;
 &lt;application path="/" applicationPool="Clr4IntegratedAppPool"&gt;
 &lt;virtualDirectory path="/" physicalPath="C:\Users\DanZe3\Documents\Visual Studio 2013\Projects\SMApplication\SMApplication" /&gt;
 &lt;/application&gt;
 &lt;bindings&gt;
 &lt;binding protocol="http" bindingInformation="*:29790:localhost" /&gt;
 &lt;binding protocol="http" bindingInformation="*:29790:192.168.1.8" /&gt;
 &lt;/bindings&gt;
 &lt;/site&gt;
</code></pre>

This won't cause any problem in a production environment.

blocks|key|4519072|text|I由于某种原因，应用程序的DefaultAppPool+(或其他自定义名称)可能已停止。确保它处于打开状态。回收也是如此。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4519073|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I
Application's DefaultAppPool (or other custom name) may have stopped for some reason. Make sure it is on. Recycle too.

I have searched every topic and it seems that everyone got there problem solved already and I have tried all the possible solution they have provided or I am still missing something.

-FireWall already turned off. 

Ok so I am trying to access my IIS server Application that is currently run by VS 2013. Update 2.

when I try to access <a href="http://localhost:29790/" rel="noreferrer">http://localhost:29790/</a> &lt;- this to <a href="http://192.168.1.3:29790" rel="noreferrer">http://192.168.1.3:29790</a> which is my current IP on my local. It gives me 503 error.

I have searched for the solution and gives my a tons of.

applicationhost.config file

<pre><code>&lt;site name="SMApplication(4)" id="10"&gt;
 &lt;application path="/" applicationPool="Clr4IntegratedAppPool"&gt;
 &lt;virtualDirectory path="/" physicalPath="C:\Users\DanZe3\Documents\Visual Studio 2013\Projects\SMApplication\SMApplication" /&gt;
 &lt;/application&gt;
 &lt;bindings&gt;
 &lt;binding protocol="http" bindingInformation="*:29790:localhost" /&gt;
 &lt;/bindings&gt;
 &lt;/site&gt;
</code></pre>

I have tried this.

"asterisk:29790:asterisk" &lt;- it doesn't show asterisk because of the text editor.

"*:29790:"

":29790:"

by chaning the bindings. But it is still not working. I restart the PC or the VS as well. But the problem is, when I try to Re open VS. VS re overwrite the applicationhost.config and Add another Binding.

As you can see in my site name="SMApplication(4) &lt;- it has 4 already. 
This is automatic when I re open the file
and then the bindings will be "*:29790:localhost" again.

Somehow Editing this bindings. VS studio will create another binding of the application. having another sitename="SMApplication(5).

I have tried to remove the localhost on the "*:29790:localhost" but when I run the application it gives me.

Unable to Launch IIS Express Web Server.
The start URL specified is not a valid. <a href="http://localhost:29270/" rel="noreferrer">http://localhost:29270/</a>
