在网络上的其他计算机上查看我的 IIS 托管站点

小开

First of all, try to connect to the LAN IP of your server. If IIS is set up with only one web site, chances are that your site is going to pop up.

If you want to access it by name, you would have to add an entry in the HOSTS file of every client PC you want to view the site with (not to 127.0.0.1 obviously, but to the local IP address of your server).

Also, your Firewall needs to be configured to accept incoming calls on Port 80.

This is usually the point where it makes more sense to set up a DNS service that you can register names like "mysite.dev" with centrally, without having to dabble with hosts files. But that's a different story, and belongs to superuser.com or serverfault.com.

127.0.0.1 always points to localhost. On your home network you should have an IP address assigned by your internet router (dsl/cablemodem/whatever). You need to bind your website to this address. You should then be able to use the machine name to get to the website, but I would recommend actually editing the hosts file of the client computer in question to point a specific name at that computer. The hosts file can be found at c:\windows\system32\drivers\etc\hosts (use notepad) and the entry would look like:

192.168.1.1     mycomputername

As others said your Firewall needs to be configured to accept incoming calls on TCP Port 80.

in win 7+ (easy wizardry way)

go to windows firewall with advance security
Inbound Rules -> Action -> New Rule
select Predefined radio button and then select the last item - World Wide Web Services(HTTP)
click next and leave the next steps as they are (allow the connection)

Because outbound traffic(from server to outside world) is allowed by default .it means for example http responses that web server is sending back to outside users and requests
But inbound traffic (originating from outside world to the server) is blocked by default like the user web requests originating from their browser which cannot reach the web server by default and you must open it.

You can also take a closer look at inbound and outbound rules at this page

Open firewall settings. Then search for something like - Allow program or feature to allow through firewall. If in the list World Wide Web services (HTTP) is unchecked, check it and restart the system.

Our machine is all set to accept inbound requests.

After installing antivirus I faced this issue and I noticed that my firewall automatically set as on, Now I just set firewall off and it solved my issue. Hope it will help someone :)

 Control Panel>System and Security>Windows Firewall>Allowed Programs-> then check all " World Wide Web Services(Http) tab".

Its worked for me

If you're hosting website on a specific port in IIS like 4321 then you'd have to allow this port through Windows Firewall too. Here're the steps that I followed along with the imanabidi's answer to get it work for me:

Windows Firewall > Advanced settings
Inbound Rules > New Rule
Select Port > Next
Specific local ports > Add the Port you want to allow
Allow All Connections
Enter a name and some description so that you remember it later on
Done

Very Late Answer but I will highlight some point as I had to deal with it years ago setting up my IIS site across network

Both your machines should be connected to the same network (same wireless network is fine)
Access your remote machine via IP 168.192.x.x or via http://his-pc-name (do not forget the http part)
This will server the default IIS page on the remote machine (same that is served through localhost). If you want to server another site, [you have to make that default] first1.

Make sure your IIS is working fine on remote machine by checking localhost which should served the default site. Also make sure your firewall is configured to allow connection via port 80 or you can just disable firewall for the time being for testing purposes.

You have to do following steps.

Go to IIS ->
Sites->
Click on Your Web site ->
In Action Click on Edit Permissions ->
Security ->
Click on ADD ->
Advanced ->
Find Now ->
Add all the users in it ->
and grant all permissions to other users ->
click on Ok.

If you do above things properly you can access your web site by using your domain.
Suggestion - Do not add host name to your site it creates problem sometime. So please host your web site using your machines ip address.

小开

It might be late, but for any other person who may get such an issue in future, for any connections you want to make to the server (in this case the machine that hosts the web application, regardless if it is iis or xampp) you need to allow connection or traffic through the specific port that will be used in the firewall

1. Go to Windows Firewall -> Advanced settings
2. Click Inbound Rules -> Then New Rule
3. Select Port -> Next
4. Specific local ports -> Add the Port you want to allow
5. Allow All Connections
6. Enter a name and a description for to help you remember later on

and you Done

In addition to modifying your firewall, don't forget to add port binding too!

Open $(SolutionDir)\.vs\config\applicationHost.config and find binding definitions, should be something like this

<sites>
<site name="Samples.Html5.Web" id="1">
<application path="/" applicationPool="Clr4IntegratedAppPool">
<virtualDirectory path="/" physicalPath="C:\Git\Samples.Html5.Web" />
</application>
<bindings>
<binding protocol="http" bindingInformation="*:63000:localhost" />
</bindings>
</site>
...
</sites>

Just add extra lines to reflect your machine IP and designated port

<bindings>
<binding protocol="http" bindingInformation="*:63000:localhost" />
<binding protocol="http" bindingInformation="*:63000:10.0.0.201" />
</bindings>

Full worked solution on 2021.

The binding with IP is not worked. The asterisk solved the problem.

<bindings>
<binding protocol="http" bindingInformation="*:63000:localhost" />
<binding protocol="http" bindingInformation="*:63000:*" />
</bindings>
