This is a continuation of my previous post titled Installing IIS 7.5, A number of Web services that were previously available as separate downloads are now integrated into IIS in Windows Server 2008 R2, as described in the following sections .

Using IIS WebDaV

Web-based Distributed Authoring and Versioning (WebDAV) is an IIS extension, now implemented as a role service called WebDAV Publishing, which expands the capabilities of the Hypertext Transfer Protocol (HTTP) by making it possible for administrators and users to publish documents on Web sites simply by copying them to a mapped network drive.  After installing the role service, you create an authoring rule that specifies what content you want to be able to publish and which users can publish it, using the interface shown. Then, using a feature called the WebDAV redirector on the client computer, you map a drive to your Web site.  Copying files to that drive automatically publishes them on the Web site.

The WebDAV implementation in Windows Server 2008 R2 is fully integrated into the IIS 7 .5 architecture, and supports the following features:

• Standard compliance - The WebDAV implementation in IIS 7 .5 is fully compliant with the Request for Comment (RFC) 4918 standard published by the Internet Engineering Task Force (IETF) .
• Site-level support - Unlike earlier versions, you can now enable WebDAV publishing at the site level, instead of on the entire server .
• Support for HTTP over SSl - This enables clients to publish documents securely by encrypting transmissions using the Secure Sockets Layer (SSL) protocol .
• Supports for locks - The WebDAV in IIS 7 .5 supports both shared and exclusive locks to prevent lost updates due to overwrites .
• Per-URl authoring rules - This enables administrators to specify WebDAV security settings for individual Uniform Resource Locators (URLs) .  This provides the ability to create different sets of security parameters for standard HTTP requests and WebDAV authoring .

Using Ftp Server

File Transfer Protocol (FTP) is one of the early protocols in the Transmission Control Protocol/Internet Protocol (TCP/IP) suite .  It was created at a time when security was not as great a concern as it is now, and as a result, it has no built-in data protection of any kind .  Clients transmit passwords in clear text, and transfer files to and from servers in unencrypted form .  Windows Server 2008 R2, however, has an FTP server implementation that is enhanced with better security measures and other new features .

The FTP Publishing Service role service included in the Windows Server 2008 release is a holdover from Windows Server 2003.  It requires you to install the old IIS 6 .0 version of the management console because it is not compatible with the new IIS 7 .0 architecture.  Soon afterward, however, Microsoft released, as a free download, a new FTP Publishing Service that was compatible with IIS 7.0.  Administrators could create and manage FTP sites using the current Internet Information Services (IIS) Manager console, and the service also included new features, such as the following:

• FTP over Secure Sockets layer (SSl)  - Enables the FTP server to establish secure connections using password protection and SSL data encryption.
• Combined FTP and Web hosting - Enables a single IIS site to support both HTTP and FTP connections.
• Virtual host naming - Enables a single IIS server to host multiple FTP sites using a single IP address and port number, distinguishing between the sites by using host names, just as it can with Web sites.
• Improved logging and error handling - IIS log files include additional fields for FTP connections, and IIS can generate detailed error messages for clients on the local network.

Now, in Windows Server 2008 R2, Microsoft has fully incorporated that FTP Publishing Service into IIS 7.5, so there is no need for a special download and no need to install an outdated management console.  They have also included an additional role service, FTP Extensibility, which enables developers to use their own managed code to create customized authentication, authorization, logging, and home directory providers.

Windows Server 2008, Microsoft introduced Internet Information Services (IIS) 7 .0, a major architectural update to its Web and application server platform .  Since then, as anticipated, the IIS development team has been working on a variety of enhancements and extensions that build on that new architecture .  Now, in Windows Server 2008 R2, Microsoft introduces IIS 7 .5 .  Although based on the same basic structure as IIS 7 .0, this new version includes numerous new features and refinements .  This chapter lists the new features in IIS 7 .5 and explains how they enhance the capabilities of the Web and ap- plication server platform .

Installing IIS 7.5

The Web Server (IIS) role in Windows Server 2008 R2 is only slightly different in appearance from that in Windows Server 2008.  When you select the role in the Add Roles Wizard, the Add Features Required For Web Server (IIS) dialog box does not appear and prompt you to install the Windows Process Activation Service (WPAS) feature, as it didin Windows Server 2008. That dependency is still there, however. Even when you don’t explicitly install WPAS, IIS 7.5 starts the service as needed.

IIS 7.5 also adds three new role services, as follows:

WebDAV Publishing, Enables users to publish content to IIS Web sites inter-actively and securely. For more information, see the section “Using IIS WebDAV,” later in this chapter.

FTP Server, Enables users to transfer files to and from an IIS server and perform basic file management tasks.

IIS Hostable Web Core, Enables developers to integrate IIS request handling functionality into their own applications .

WebDAV Publishing and FTP Server were both add-on products for IIS 7 .0 that administra- tors had to download and install separately. Now, in Windows Server 2008 R2, they are both fully integrated into the Web Server (IIS) role, and you can install them as part of IIS 7.5.

Using Microsoft Web platform Installer

Although Windows Server 2008 R2 administrators can still install IIS and create Web sites in the traditional manner, using the Server Manager and Internet Information Services (IIS ) Manager consoles, Microsoft now provides another way. The Microsoft Web Platform is an integrated set of servers and tools that enable you to deploy complete Web solutions, includ- ing applications and ancillary servers, with a single procedure. The Microsoft Web Platform Installer is a tool that enables you to select, download, install, and configure the features you want to deploy on your Web server.

The Web Platform Installer file you download is a stub, a tiny file that enables you to select the modules you want to install and then to download them, using the interface shown in Figure 7-1. Unlike the Web Server (IIS) role in Windows Server 2008 R2, the Web Platform Installer enables you to download other servers and applications that are produced by Microsoft and third parties. The installer provides a selection of collaboration, e-commerce, portal, and blog applications, and enforces the dependencies between the various elements. If, for example, you select an application that requires a database, the installer will download and install SQL Server Express 2008, Microsoft’s free SQL database product.

During the installation process, Web Platform Installer prompts you for information needed by your selected applications, such as what subdirectory to install them into, what passwords to use, and so on. When the process is complete, you have a fully functional Web site, complete with IIS and applications and ready to use .

Using the IIS Web Deployment tool

The Web Deployment Tool (formerly called MS Deploy) is an IIS extension that enables administrators to package entire Web sites, Web servers, and applications for deployment on other computers, or just for backup purposes.  Packages include all of a site’s content, includ- ing configuration settings, permissions, databases, and certificates.

When you run the Web Deployment Tool offline, it adds a Manage Packages section to the Actions pane of the Internet Information Services (IIS) Manager console.

Selecting a server, site, or application and clicking Export Application launches a wizard in which you can select the elements that you want to export.  The wizard then creates a package in the form of a Zip file, which contains the original content plus configuration settings in Extensible Markup Language (XML) format

The package file now contains a complete copy of the server, site, or application you selected. You can save the package file to function as a backup or an archive of the site’s current configuration, or copy it to another IIS server running the Web Deployment Tool and import it. The tool also includes a Remote Agent Service, which administrators can use to synchronize Web servers in real time over a network connection. This enables you to replicate sites and servers on a regular basis so that you can create Web farms for load balancing and fault tolerance purposes

Today post will cover about one of IIS 8 new feature. It is called Application Initialization module. Activating it allows you to enable the following capabilities:

• Starting a worker process without waiting for a request (AlwaysRunning)
• Load the application without waiting for a request (preloadEnabled)
• Show a loading page while the application is starting

To enable these features

1. Set the startMode on the application pool  to AlwaysRunning.

    <system.applicationHost>    
     <applicationPools>      
      <add name="DefaultAppPool" autoStart="true" startMode="AlwaysRunning" />    
     </applicationPools>  
    </system.applicationHost> 

2. Set preloadEnabled to true on the web application.

    <system.applicationHost>    
     <sites>      
      <site name="Default Web Site" id="1">        
       <application path="/">          
        <virtualDirectory path="/" physicalPath="%SystemDrive%\inetpub\wwwroot" />        
       </application>        
       <application name="AppInit" applicationPool="DefaultAppPool" preloadEnabled="true">          
        <virtualDirectory path="/AppInit" physicalPath="c:\inetpub\wwwroot\appinit" />       
        </application>      
      </site>    
     </sites>  
    </system.applicationHost> 

Changing the startMode to AlwaysRunning will start the application pool and initialize your application the moment your IIS server is (re)started. So users that visit your site don’t have to wait because the worker process is already started.

By setting preloadEnabled to true, it starts loading the application within that worker process without waiting for a request.

Server Name Indication (SNI) is an extension to the TLS protocol that includes the hostname during the handshaking process. This allows for a web server to host multiple SSL-enabled web sites using one IP address. Prior to IIS 8, it was not possible to use this capability in IIS.

Configuration

SNI is enabled in IIS by default. To use this capability, simply provide the appropriate hostname in the configuration of the HTTPS binding for a site.

Each HTTPS binding that you would like to use SNI with should have the host name provided. All bindings should have the option for "Require Server Name Identification" checked except fot the site you would like to act as the "default" HTTPS site. Just as is the case with HTTP bindings, this is the site that will be used when a client does not provide a host header as part of the request. If you do not have at least one HTTPS binding with the option unchecked, IIS Manager will issue a warning informaing you of that fact.

Compatability

Before using SNI with IIS 8, you should be aware of the client requirements for this to work properly. Specifically, the TLS library used by an application must support SNI and the application must pass the hostname to the TLS library when making requests. The following web browsers support SNI:

• Internet Exmplorer 7 or later running on Windows Vista or later
• Google Chrome (6.0 or later requird if running on Windows XP, 5.0.342.1 or later if running on OS X 10.5.7 or later)
• Mozilla Firefox 2.0 or later
• Safari 3.0 or later (Vista or later and OS X 10.5.6 or later)
• MobileSafari running on iOS 4.0 or later
• Opera 8.0 or later

Are you getting the following error when configuring the IIS8 connector for CF10 on Windows Server 2012 or Windows 8?

"Version 8.0 is installed. Supported versions are 4.x, 5.x, 6.x, 7x"

We have some additional guidance that should help you work around it.

1) Please make sure that you are using correct Windows 2012 Server/Windows 8 supported ColdFusion 10 installer (The updated full ColdFusion 10 Installers)

MD5s of the full installer should be as follows:

For Win 64-bit MD5 --> ef74d583a8d069c7138a4ea8da9c5359

For Win 32-Bit MD5 --> ca9363a0a3817533436238b477b88792

2) You can opt to configure IIS 8 while installing or after installation.

     Installer has in-built support for IIS 8 on Win 8/Win 2012.

3) By all means install the latest CF10 updates, but do not apply updates older than Update 8. If you apply any of the older updates like update 7 or 6, you will likely see the following error while trying to run the IIS 8 web server connector:

"Version 8.0 is installed. Supported versions are 4.x, 5.x, 6.x, 7x" 

4) If all the above steps have been followed and if you are still getting the error, please verify that update 8 is installed properly by checking the log file under \cfusion\hf-updates\hf-10- 00008\Adobe_ColdFusion_10_Update_8*.log

And MD5  of the connector jar located at <CF10_Install_Home>\cfusion\runtime\lib\wsconfig.jar should be

     a) If you have applied Update 8 -> ba8f8c8bcd34c266faa0031107bbf948.

     b) If you have NOT applied any Updates -> 35cc2f630325506081f3b29d41e50c3c

Internet Information Services (IIS) 8.0 Express is a free, simple and self-contained version of IIS that is optimized and available for developers. IIS 8.0 Express makes easy to use the most current version of websites tools like Visual Studio and WebMatrix. IIS 8.0 Express has all the core features of IIS as well as additional features for easy website development which includes:

- IIS 8.0 Express doesn't run as a service or require administrative privileges to perform most tasks.
- IIS 8.0 Express allows Multiple Users to work independently on the same computer.
- IIS 8.0 Express works well with ASP.NET and PHP applications.

IIS 8.0 is only available in Windows Server 2012 and Windows 8. It includes Application Initialization, centralized SSL certificate support, multi core scaling and also other new features.

Previously, we have discussed about new features in IIS 8. Now I will show more information about this new features.

1. FTP Logon Attempt Restrictions

This module ensures the security and manageability. Due to this feature you can now use greylisting and access patterns enabling you to smoothly and dynamically manage access for number of sites to the internet and FTP servers.

2) Improved CPU Throttling

In IIS8 there are kernel level changes to support real CPU throttling. There are two actions possible for sites that reach the CPU threshold. These are:

• Throttling is based on the user and not specifically on the application pool. The throttle feature will keep the CPU for a particular worker process at the specified level.
• Throttle under load will allow a site to use all possible CPU, while throttling the worker process if the server is under load. If you used WSRM (Windows System Resource Manager) in the past, you no longer need to do so.

3. Application Initialization Module

Priorly known as the application warm-up module which was used for a time, and now it is completely ready as Application Initialization Module. This allows loading sites and pages before the traffic arrives and handling of requests in a friendly and more smoother way while the application first loads. It is possible to set up home page or use URL rewrites.

4. SSL scalability

In previous versions of IIS each SSL (Secure Socket Layer) site required its own IP address, and since each certificate was loaded into the memory on the first visit to an SSL site, startup performance can be slow. In IIS8 the SSL certificate is easily scalable to thousands of secure sites per system because only the certificate that is needed is loaded. Additionally, also loading of large numbers of certificates is essentially improved.

5. SNI / SSL host header support

Using host headers and a shared IP address with SSL certificate has always been ambiguous. IIS8 now offers Server Name Indication (SNI) support through which many SSL sites can share the same IP. SNI is a pretty new feature which allows host headers to work with SSL. The most recent browsers are supporting SNI.

6. Use ASP.NET 3.5 and 4.5

IIS 8.0 on Windows Server 2012 runs ASP.NET applications on all .NET Framework versions supported on Windows Server 2012. This means ASP.NET applications can run on IIS 8.0 using either .NET Framework 3.5, or .NET Framework 4.5. IIS 8.0 hosts versions of the .NET Framework in different application pools, thus allowing multiple ASP.NET applications with different .NET Framework versions to run simultaneously on Windows Server 2012.

7. Web Sockets

Allows you to build more interactive and powerful web applications because of a continuous and bidirectional communication between the web browser and the web server. Web Sockets require Windows Server 2012 or higher versions.

8. Dynamic IP Restriction (DIPR)

With DIPR we can Customize IIS reply like Unauthorized (HTTP 401), Forbidden (HTTP 403), Not Found (HTTP 404), or Abort (IIS terminates the HTTP connection). Also we can allow or deny specific IP address or a range of IP addresses, even if they violate a dynamic restriction setting. We can block dynamic IPs based on the number of concurrent requests or the number of requests over a period of time.Finally it is a very useful feature for web servers behind firewall, because of the proxy mode property that enables IIS to cross checks the values in the X-Forwarded-For HTTP header. So it can verify the IP address of the client who initially made the request.

9. Multicore Scaling on NUMA hardware

Internet Information Services (IIS) on Windows Server 2012 supports Multicore Scalling on NUMA hardware and provides the optimal configuration for the IT administrators. Following options describes the different configuration options to achieve the best performance with IIS 8.0 on NUMA hardware.IIS supports following two ways of partitioning the workload:

• Run multiple worker processes in one application pool: If you are using this mode, by default, the application pool is configured to run one worker process. For maximum performance, you should consider running the same number of worker processes as there are NUMA nodes, so that there is 1:1 affinity between the worker processes and NUMA nodes. This can be done by setting "Maximum Worker Processes" AppPool setting to 0. Due to this setting, IIS determines how many NUMA nodes are available on the hardware and starts the same number of worker processes.
• Run multiple applications pools in single workload/site: In this configuration, the workload/site is divided into multiple application pools. For example, the site may contain several applications that are configured to run in separate application pools. Effectively, this configuration results in running multiple IIS worker processes for the workload/site and IIS intelligently distributes the processes for maximum performance.

Hello all, sometimes I find in forum that people complain about Error 404.3 – Not Found. I decided to write the post about this issue and hope it will solve your problem.

Hmm… I assume that you have installed Windows Server 2012. When you upload your files, try to browse your site, you see this error:

One of the issues might be :

It complaints about missing handler mappings for the created web site. this is obvious when you look at it closely as follows

Go to the Desired web application listed under "Default web site" under IIS 8 and open "handler mappings"

Here most of the handler mappings are not listed. As a remedy to this click "Revert to Parent" and you will see the all handler mappings are inherited from the parent node.

This might solve the 404.3 error that you get

This blog cover brief information how to host your WCF service in IIS8 (Windows Server 2012).

Here is the solution.

Server Roles

1. First make sure you have enabled IIS function and .net 3.5 in Features.
For the IIS features, please remember to enable ASP.NET3.5 and ASP.NET 4.5

2. Second, check the IIS Hostable WebCore
3. Finally, I think the most important is this:

Check Application Sever->Web Server (IIS) Support

I have also check the HTTP Activation in Windows Process Activation Service Support, but I do not know if it is required.

For the freatures,

1. Check all items in .NET 3.5
2. Check WCF Service in .NET 4.5

That’s it.

Last but not least, I have register the WCF Service from

C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation\ServiceModelReg.exe –i

Run the above in command line.

This article discuss brief information about the improvements in IIS 8. Internet Information Services (IIS) 8 includes many new and improved features that make moving to Windows Server 2012 compelling for organizations that rely on Windows Servers as their web server.

Improvement 1: Centralized SSL Certificate Management

With IIS on Windows 8 or Windows Server 2012, you can take advantage of the SSL certificate management console. This is a central management console that is able to install certificates and work with certificates across all IIS 8 web servers.

This includes the ability to more rapidly bring new servers online by being able to import all certificates that are needed. If a certificate needs to be renewed on multiple systems, it can be done through the IIS 8 certificate management console. You no longer have to log onto each system to update the certificate.

Note: Centralized SSL Certificate management is installed as a separate feature. You can install IIS without Centralized SSL Certificate Support. Centralized SSL Certificate Support is in the security section of “Windows Features.”

Improvement 2: Application Initialization

One frustrating problem that many web server admins face is the problem of slow-responding sites as web applications are initializing. A common workaround is to use tools and scripts to “cold start” the applications early in the morning so that the sites are ready to perform: The in-memory cache is loaded, and in some cases the content must be generated, before the IIS server is ready to respond to HTTP requests.

With IIS 8, Application Initialization lets you establish rules for “warming up” sites. For example, you can have larger applications begin the initialization process earlier than smaller applications. You can also configure through application initialization a new splash screen to be displayed in case people find themselves waiting while the application is initializing.

I can see a much better user experience by logging onto a SharePoint site early in the morning and having the first page displayed being a simple “Please wait while this application is being prepared for use” splash screen instead of just a blank page and a spinning circle.

Improvement 3: Dynamic IP Address Restrictions

Restricting access to a website by its IP address is nothing new -- admins have long been able to do that. You can even restrict by a block of IPs in an address range.

The problem that persists is tracking down all of the IP addresses to block. This would usually take a long time of parsing through logs, and even if going through the logs and filtering out the IP addressed were scripted, it is done in a reactive manner.

Instead, using the Dynamic IP Address Restrictions feature in IIS 8 for Windows 8 and Windows Server 2012, you can specify on a per web application level the maximum number of connections that an IP address can create within a certain time frame. And you can also specify the maximum number of attempts that can be made into the IIS 8 server from an IP address within a specific time. Any attempts beyond what is allowed are automatically filtered out, making your web applications and your web server much more resistant to malicious activity.

Dynamic IP Address Restrictions is added as an additional feature of IIS that is not installed by default. To install the feature, open Windows Features, then place a check in the box to select Web Server (IIS) -> Web Server -> Security -> IP and Domain Restrictions. After all that, click Finish.
