Configure and Setup remote server application and web.config in IIS Server

We need setup Server project assembly in IIS.

Step 1: Go to the primary web root directory C:\Inetpub\wwwroot and create a new folder named Server.

Step 2: Inside folder Server, create a new folder named bin. Now, move to your project Debug directory (IServer\Server\bin\Debug). Copy all files from here and place them into \wwwroot\Server\bin.

At this point the wwwroot\Server\bin directory may have the following files:

Figure 1: File structure in \server\bin folder in web root directory

Step 3: We need a web config to enable the assembly to work as remote objects. Create a file web.config in the \Server folder. Open web.config in notepad and add the following content in it.

Listing 3: Content of web.config for server in IIS

<?xml version="1.0" encoding="utf-8" ?>
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
<system.runtime.remoting>
    <application>
 
        <service>
            <wellknown mode="Singleton" type="Server.clsServer,Server"
                               objectUri="server.soap" />
        </service>
        <channels>
            <channel ref="http" />
            <serverProviders>
                <formatter href="binary" />
            </serverProviders>
        </channels>
    </application>
</system.runtime.remoting>
</configuration>

Save web.config file. At this point the wwwroot\Server\ directory may look like:

Figure 2: File structure in \server folder in web root directory

Step 4: We need setup Server folder as a virtual directory in IIS. Open the IIS window as: Control Panel >> Administrative Tools >> Internet Information Services.

Expand the node to reach to the folder Server: Local computer >> Web Sites >> Default Web Site >> Server.

Right click on COMAppASPClient and open the properties window.

Click "Create" button in the application name tag. This makes the directory a virtual directory.

Figure 4: Creating the server folder to be a virtual directory

Click OK to finish with the IIS Server properties window. Here the remote object is installed. Let us test whether it is successfully installed. Open an internet explorer window and write the following in URL (use server name/ip instead of localhost if remote server is installed on other machine in LAN/WAN).

http://localhost/server/server.soap?wsdl

Opening this link would show information in XML format about implemented remote methods on the page as given below.

Figure 5: Get the description of remote object services in XML format

If you get the XML output on the page about the remote service then you could be sure that remote server object is installed in IIS correctly. Now we can proceed to create a web client which consumes these services.

Title: Another cause of 404   
Name: Tangent
Date: 2011-03-31 9:47:15 PM
Comment:
Occasionally 404 can be caused by too much data has been sent to remoting server. Because there is a maxAllowedContentLength constraint which is by default set at 4MB, unless this setting is overridden, calling Remoting with serialized data potentially larger than 4MB would result a 404 error (non-sense but true). Check http://tangentlin.wordpress.com/2011/03/31/404-error-in-net-remoting/ for more details and solution.

Ok, It work well base on your description, But there are a mistake need to point out which in Web.config
"type="Server.clsServer,Server"

Not "clsServer", First I don't change it,it should be a Class "MyServer" in here, or else throw a exception:"Cannot load type Server.clsServer, Server Pin", Hope can help others.
Anyway, Good work with your clear explanations.

.NET remoting is actually great for free services we're hoping to provide like online radio stations where we're not considering security much. Still if we need to include sort of security it's better deal with IIS than .NET remoting.
I Appreciate good work with your clear explanations.

If you are getting a 404 error it means probably a mapping for the .REM extension doesn't exist or isn't mapped to the aspnet_isapi.dll I'm guessing you installed .NET prior to loading IIS, because it is done with the installation.

From the .NET command prompt run the following
aspnet_regiis -i

Thanks a lot for your article, some days wandering and i found only generic help. This article step by step guided me to a working solutions. Just two tips:
- explain better what you write in the web.config
- explain better the ways in which an ASP.NET page can call you (through global.asax activation and so on)

Thanks again,
Fabrizio

this is actually for advance programmers only. In normal situation we don't require to host remoting under IIS. It's for hight level busineess processing.

Title: for C# version

you can easily get C# version of code. Just try to use some convertor available free on internet. You need to put part of vb code and then you will get C# version of that code..
then use that code in your C# project.
