How to implement Windows authentication and authorization in ASP.NET

This step-by-step article describes how to implement Windows authentication and authorization in an ASP.NET application. To use the built in security of Windows and ASP.NET, implement Windows authentication and authorization on groups and users. To use Windows authentication, you must adjust settings in both Microsoft Internet Information Services (IIS) and the ASP.NET application Web.config file.

Requirements

  • Microsoft Windows 2000 Professional, Windows 2000 Server, Windows 2000 Advanced Server, or Windows XP Professional
  • Microsoft .NET Framework
  • Microsoft Internet Information Services (IIS)
  • Microsoft Visual Studio .NET

Authentication and authorization

Windows authentication and Windows authorization are two terms that are frequently interchanged. However, they do not have the same meaning. Windows authentication permits the recipient to determine the user's identity. Windows authorization determines the resources to which a user may gain access.

Configure Web application for Windows authentication

To configure your Web application for Windows authentication, follow these steps:

  • Create an ASP.NET Web Application named ASPNETWinAuth. By default, theWebForm1.aspx file appears.
  • In the HTML view of WebForm1.aspx, replace the existing code with the following sample code:

    <%=User.Identity.Name%>

  • Click Start, point to Programs, point to Administrative tools, and then click Internet Information Services.
  • The Internet Information Services MMC appears. Expand Computer, and then expand a Web site that uses Windows authentication.
  • Click the ASPNETWinAuth Web site application.
  • On the Action menu, click Properties.
  • In Properties, click the Directory Security tab.
  • Under Anonymous access and authentication control, click Edit.
  • In Authentication Methods, click to select Integrated Windows authentication. Click to clear all other check boxes.
  • Click OK.
  • In Properties, click OK. The ASPNETWinAuth Web application is now configured to accept valid user accounts.

Configure the ASP.NET application

After you configure the IIS Web site for Integrated Windows Authentication, you must configure the ASP.NET application to recognize authenticated users. To do this, you must change the Web.config file. In the Web.config file, locate the <authentication> tag, and then set the mode attribute to Windows, as in the following example:

<authentication mode="Windows" />

Test authentication

To test your Windows authentication setting, follow these steps:

  • In Microsoft Internet Explorer, view the WebForm1.aspx page. This page is located in the Http://Localhost folder. For example:

    http://Localhost/ASPNETWinAuth/WebForm1.aspx

  • Because Integrated Windows Authentication uses the current Windows user information on the client computer for the authentication, it does not immediately prompt the user for a user name and password. However, if the authentication exchange cannot identify the user, a dialog box appears that prompts the user for a Windows user account user name and password.
  • Type a valid user name and password. When the page loads, your user name appears in the following format:

    Domain Name\User Name

Restrict access

In ASP.NET, you set authorization to the application by adding settings in the Web.config file. You can specify which users or groups are permitted to have access to what resources as follows:
To permit all users of an NT Group named Managers to have access to your resources, use the following code:

<configuration>
      <system.web>
        <authorization>
          <allow roles="domainname\Managers" />
          <deny users="*" />
        </authorization>
      </system.web>
    </configuration>

To permit only specific users to have access, use the following code:

<configuration>
      <system.web>
        <authorization>
          <allow users="domainname\user1,domainname\user2,domainname\user3" />
          <deny users="*" />
        </authorization>
      </system.web>
    </configuration>

Note You can specify multiple roles or users by using a comma separated list. Verify that you use the correct case when you specify the configuration file element and the associated attribute values. This code is case sensitive.

Windows Hosting - ASPHostPortal.com :: How to change DNS Servers in Windows 7

clock October 24, 2016 08:31 by author Armend

This article is for people to change their Windows 7 DNS settings.  It will also override the DNS settings sent through DHCP so it is acceptable for most users of Windows 7.  You will need admin rights in order to preform some of these steps.
1. Choose two or more IP addresses from here, then open the Control Panel and click on Network and Sharing Center as seen below.

2. Click “Change Adapter Settings” in the left bar.

3. Right click on your network device and choose properties. In my case this was Local Area Connection, but it could also be a wireless adapter or named something else.

 

4.  Choose the IP version you would like to set the DNS settings for and click “properties”.  I will be choosing IPv4 for this guide, but the steps are basically identical for IPv6.

5.  In the window that pops up, click “Advanced” in the bottom right of the windows

6. Click the “DNS” tab at the top.

7. Click Add and then type a Tier2 server IP in the box that pops up and click add again.
You may repeat the add step as many times as you want to add more DNS servers. DNS servers added to the list are being tried consecutively after a short timeout when one or more of them are offline.
8. Click OK until you are out of dialogue boxes!

Simple Tips to Help Diagnose and Prevent Windows Server Crashes

In an enterprise setting, server failures are never an issue to be taken lightly. Since servers are the backbone of most modern operations, being able to pinpoint the cause of errors rapidly is an essential skill for any Windows server administrator. Fortunately by following a few simple steps you can easily pinpoint the cause of most Windows Server errors.

Best Practice Analysis Automation

In Windows Server 2008 R2, Windows Server 2012 and Windows Server 2012 R2, Microsoft has included a tool known as the Best Practices Analyzer (BPA). BPA is an automated scanner which when run will check your server to ensure that it is configured for optimal performance, reliability and maximum security. While this tool is not a substitute for keeping atop of Windows Server trends, BPA helps to ensure that the most commonly exploited violations are blocked on your servers.

Proactive Actions to Simplify Troubleshooting

Enable Kernel Crash Dumps

One of the most important debugging tools within Windows is the kernel crash dump file. This file typically contains all the information necessary to pinpoint the cause of a server issue. Unfortunately this feature isn’t configured by default, making it crucial that you enable this feature before experiencing issues.
To enable this feature, follow the steps below:

  • Go into:  Control Panel > System and Security > System.
  • Click Advanced system settings.
  • Under Startup and Recovery, click Settings
  • In the box that pops up, under Write Debugging Information you can specify the location for the crash dump file
    • Additionally you can have crashes added to the Windows Event Log, and you can also trigger a restart automatically upon a crash

Enable Keyboard Crash Dump Commands

After configuring the Windows crash dump settings, you will need to setup Windows to enable your keyboard to cause a system crash.
With PS/2 keyboards, you must take the following steps:

  • In the registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\i8042prt\Parameters, create a value named CrashOnCtrlScroll
  • Set it equal to a REG_DWORD value of 0x01.
  • Restart your system

With USB keyboards, you must take the following steps:

  • In the registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\kbdhid\Parameters, create a value named CrashOnCtrlScroll
  • Set it equal to a REG_DWORD value of 0x01
  • Restart your system

Windows Debugging Tools

To help with common issues that might come up as a server administrator Microsoft has released multiple debugging tools to make the job easier.

Sysinternals Suite

The Sysinternals suite is like a Swiss Army knife for your troubleshooting efforts. This collection of seventy tools maintained by Microsoft ensures that you can easily pinpoint the source of virtually any error and take action accordingly. While this suite is best installed on a thumb drive to be used when errors occur, you can also load this suite on your servers early on as a proactive measure.

While there are many tools within the suite, there are a couple which you should keep on mind;

  • Disckmon – this tool monitors, logs and displays all hard disk activity on a Windows system. By using this tool, you can better pinpoint errors which might be caused by pending hard disk failures.
  • Procdump – this tool allows you to monitor applications for CPU spikes and generating crash dumps during a spike. Additionally the tool can serve as a general dump utility which can be included in other scripts. By using this tool, you can greatly expedite the process of diagnosing troublesome applications and figuring out where to start debugging efforts.
  • TCPView – this tool allows you to view detailed listings of all TCP and UDP endpoints on your system. By using TCPView, you can pinpoint server issues to specific ports, allowing you to more in-depth action accordingly.

Windows Memory Diagnostics

Since RAM is one of the most used components of any server, many system failures often are due to memory-related matters. While typical memory issues involve applications using too much resources, or a process running out of control, failing hardware also can be responsible for system crashes. Fortunately you can easily diagnose potential memory trouble spots by using the Windows Memory Diagnostics tool built into most modern Windows Server editions.

  • To use this tool, simply open the command prompt and use the following command C:\mdsched
  • From there, you should follow the prompts to complete the diagnostic process.

The Importance of Backups

Even with the best tools and skills, occasionally a professional will encounter an issue which is beyond repair. When situations such as these occur, having a solid backup system always pays off. Although there are many backup tools on the market, Windows has a backup tool built in which can be used to protect yourself from even the worst disasters.
For details on implementing Windows Backup in windows Server 2008 and Windows Server 2012, Microsoft has documentation here.

Clustering as a way to Mitigate Risks

Server clustering is the process of having a group of independent servers working together as a single system to deliver more reliability to your users. Such arrangements are designed to protect against the following types of failure:

  • Applications and service failures which can affect software and essential services
  • System and hardware failures which can affect low level server components
  • Site failures in multisite organizations  which can be caused by natural disasters and other significant situations
  • By using clustering, you can ensure that when disaster strikes, your systems can continue operating instantly by shifting responsibility from the failed systems to the functional ones.

Conclusion

Although there are many variables which impact the reliability of your Windows servers, by focusing on proactive actions to mitigate damage you can avoid the difficulties of troubleshooting server issues. Even with the best precautions however, failures still occur, which is why you should familiarize yourself in advance with the technologies Windows provides to make the debugging process much easier.
