blocks|key|953575|text|只有一件事对我有效。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|953576|使用*:portnumber:*并不好。是的，在这样做并确保Windows防火墙打开后，我可以连接到端口，但我仍然收到"503“错误。|offset|length|style|CODE|953577|我在本地测试了一些东西，发现只有http://localhost可以工作。使用真实的IP地址(不是127.0.0.1，而是192.168.1.50)，即使在本地机器上也会返回503。我尝试在绑定中使用真实主机名，但IIS+Express拒绝启动。这实际上可能与主机名的解析方式有关。我没有进一步探讨这一点。|953578|最后，我最终使用了这个配置：|953579|<binding+protocol="http"+bindingInformation="*:53351:localhost"+/>
<binding+protocol="http"+bindingInformation="192.168.1.50:53351:*"+/>|code-block|syntax|javascript|953580|通过这种方式，我能够使用http://192.168.1.50:53351从远程机器进行连接。|953581|entityMap|0|LINK|mutability|MUTABLE|url|http://localhost/^0|0|2|E|0|G|G|0|0|0|0|C|P|0^^$0|@$1|2|3|4|5|6|7|10|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|11|8|@$D|12|E|13|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|14|8|@]|9|@$D|15|E|16|1|17]]|A|$]]|$1|J|3|K|5|6|7|18|8|@]|9|@]|A|$]]|$1|L|3|M|5|N|7|19|8|@]|9|@]|A|$O|P]]|$1|Q|3|R|5|6|7|1A|8|@$D|1B|E|1C|F|G]]|9|@]|A|$]]|$1|S|3|-4|5|6|7|1D|8|@]|9|@]|A|$]]]|T|$U|$5|V|W|X|A|$Y|Z]]]]

There was only 1 thing that worked for me. 

using <code>*:portnumber:*</code> was no good. Yes, after doing that and making sure the Windows Firewall was open, I could connect to the port, but I still got the "503" error.

I tested a few things locally, and discovered that only <a href="http://localhost">http://localhost</a> worked. Using the real IP address (not 127.0.0.1, but, for instance, 192.168.1.50), still returned a 503 even on the local machine. I tried using the real host name in the bindings, but IIS Express refused to start. This may actually have something to do with how the host name was being resolved. I didn't explore that further.

Finally, I ended up using this configuration:

<pre><code>&lt;binding protocol="http" bindingInformation="*:53351:localhost" /&gt;
&lt;binding protocol="http" bindingInformation="192.168.1.50:53351:*" /&gt;
</code></pre>

In that way, I was able to connect from a remote machine using <code>http://192.168.1.50:53351</code>.

Found the problem had to do with a bad urlacl mapping. To figure this out:

<pre><code>netsh http show urlacl 
</code></pre>

and look for things like <code>http://+:80/</code> or the port you are binding to.

Then use 

<pre><code>netsh http delete url=&lt;the url from the list&gt;
</code></pre>

This fixed the problem for me.

blocks|key|953691|text|帮助我的是，右键单击“IISExpress”图标，“显示所有应用程序”。然后选择网站，我看到它使用的是哪个aplicationhost.config，更正进行得很完美。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|953692|​|953693|📷|atomic|offset|length|953694|953695|entityMap|0|IMAGE|mutability|IMMUTABLE|imageUrl|https://ask.qcloudimg.com/http-save/yehe-900000/9b6fb67d23135940a807903f6af0f366.jpeg|imageAlt^0|0|0|0|1|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|T|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|U|8|@]|9|@$G|V|H|W|1|X]]|A|$]]|$1|I|3|C|5|6|7|Y|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Z|8|@]|9|@]|A|$]]]|K|$L|$5|M|N|O|A|$P|Q|R|-4]]]]

What helped me, was right clicking the 'IISExpress' icon, 'Show All applications'. Then selecting the website and I saw which aplicationhost.config it uses, and the the correction went perfectly.

blocks|key|953752|text|问题在于更新web文件夹中的applicationhost.config文件，而不是更新解决方案的文件夹。需要更改的是解决方案配置文件|type|unstyled|depth|inlineStyleRanges|entityRanges|data|953753|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|$]]

The problem is updating the applicationhost.config file inside the web folder instead of the solution's. The solution config file is the one to change

blocks|key|737808|text|关于Anthony+Rizzolo的回答:在Windows+8.1中，我必须这样输入：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|737809|netsh+http+delete+urlacl+url=<the+url+from+the+list>|code-block|syntax|javascript|737810|例如：|737811|netsh+http+delete+urlacl+url=http://%2B:8689/|737812|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

Regarding Anthony Rizzolo's answer: in Windows 8.1, I had to type like this:

<pre><code>netsh http delete urlacl url=&lt;the url from the list&gt;

For example:

<pre><code>netsh http delete urlacl url=http://+:8689/

This fix it for me.

I'm attempting to test a website I have running in a local IISExpress instance with some other machines / devices on my local network. I am running Win7 Pro.

When I first attempt to browse to my machine from another machine on my local network segment, I get a 400 error: Hostname is invalid.

I understand that I need to grant remote access to the ACL with a command on the elevated command prompt like:

<code>netsh http add urlacl url=http://mymachinename:50333/ user=everyone</code>

Now I get a 503 service is unavailable error. 

Windows Firewall is currently shut off, and I am able to browse my local IISExpress instance with the address <code>http://localhost:50333</code>

What is the final piece to this configuration puzzle?
