Installing IIS 7 on Windows Vista and Windows 7

by IIS Team

Introduction

Advances in cloud technologies have led many users to use Windows Azure Web Sites to host both a production site and test site, as it makes it easy to test various configurations without impacting their own personal computers. If you still prefer to do this on your desktop, you can install IIS on it, as well as other applications and extensions easily using the Microsoft® Web Platform Installer (Web PI). To learn more about the Web PI, see Learn about and install the Web PI.
If you choose to install IIS 7.0 or above manually, you can use this article for guidance.

Before You Begin

Ensure that you have installed one of the editions of Windows Vista or Windows 7 on which IIS 7 and above is supported before you proceed. Not all IIS features are supported on all editions of Windows Vista and Windows 7. Home Basic and Starter editions include only limited basic features of IIS. To see a list of which features are supported on the edition of Windows you are using, see one of the following:
Also be sure that you have administrative user rights on the computer. By default, you do not have administrative user rights if you are logged on as a user other than the built-in administrator, even if you were added to the local Administrators group on the computer (this is a new security feature in Windows Server® 2008 called Local User Administrator). Log on either to the built-in administrator account, or explicitly invoke applications as the built-in administrator by using the runas command-line tool.
Note that you can run runas /user:administrator cmd.exe so that every application you run from that command line will be elevated, eliminating the need to use the runas syntax from that command line.
If you are logged on to an account other than the built-in local administrator account, you may see the following security alert dialog box.

If you want to use ASP, Microsoft® ASP.NET, or PHP, install the modules needed to host these pages; this can be done during the installation of IIS or after the installation is complete.

Use Unattended Setup to Install IIS 7.0 and above

IIS can also be installed unattended on Windows Vista. For detailed instructions and scripts, see Using Unattended Setup to Install IIS 7.0 and Above.

Classic ASP Script Error Messages No Longer Shown in Web Browser by Default

In earlier versions of IIS, error messages from classic ASP scripts were sent to a Web browser, by default. Because these error messages might reveal sensitive information to malicious users, IIS 7 and above disables this feature by default. When your classic ASP scripts encounter an error in IIS, you receive the following error message by default:
console
An error occurred on the server when processing the URL. Please contact the system administrator.

If you are the system administrator please click here to find out more about this error.
You can customize the ASP script error message, and also determine whether to return the script errors to a Web browser.
 Note
As a best practice for security, you should only enable sending ASP script error messages to a Web browser on a development or test computer; returning script error messages to a Web browser can unintentionally expose more information than you intended to show.

Working with User Access Control

You need to make sure that you follow the steps in this document by using an account that has full administrative permissions. This is best accomplished by using one of two methods:
  • Log in to your computer by using the local administrator account.
  • If you are logged in using an account with administrative permissions but that is not the local administrator account, open all applications and all command prompt sessions by using the "Run as Administrator" option.
These above conditions are required because the User Account Control (UAC) security component in Windows Vista and Windows Server 2008 will prevent administrative access to the IIS configuration settings. For more information about UAC, see the following documentation:

Customizing Classic ASP Error Messages

The configuration settings that you use to customize these settings are in the following list:
  • scriptErrorMessage: This is an optional string attribute that specifies the error message that will be sent to the browser when specific debugging errors are not sent to the client.
  • scriptErrorSentToBrowser: This is an optional Boolean attribute that specifies whether the writing of debugging specifics to the client browser is enabled.
You can configure these settings by using IIS Manager. To do so, open IIS Manager and navigate to the site or application where you want to enable or disable script messages, and then double-click the ASP feature.
In the list of ASP features, configure the Script Error Message and Send Errors To Browser options.
You can also configure these settings by using the command-line tool AppCmd.exe with the following syntax:
console
appcmd.exe set config "Default Web Site" -section:system.webServer/asp /scriptErrorMessage:"An error occurred."
appcmd.exe set config "Default Web Site" -section:system.webServer/asp /scriptErrorSentToBrowser:"False"

More Information

For additional information about the options that are available for classic ASP debugging, see the following page in the IIS configuration reference on the Microsoft IIS.net Web site:
As an alternative to returning ASP script error messages to a Web browser, you can enable Failed Request Tracing on your server. For example, you could add a rule to trace HTTP 500 errors automatically, which the ASP engine generates when an error occurs. By analyzing the output in the Failed Request Tracing logs on your server, you can pinpoint the source of classic ASP errors. As an additional security note, Failed Request Tracing logs are not available to Web browsers, so the troubleshooting information is only available on your server. If you use Failed Request Tracing, it will also let you troubleshoot unmonitored classic ASP errors in detail without having to reproduce the errors.

Server DNS Address Could Not Be Found

Server DNS Address Could Not Be Found [SOLVED] from drivereasy.com

By Camilla Mo  in Network issues Tags: network
If you use Google Chrome and you’re getting the “server DNS address could not be found” error message when you try to visit some websites, don’t worry! It’s definitely something you can fix…

Here are 5 fixes

Here are five fixes to try that have solved this problem for other Chrome users. You may not need to try them all. Just work your way down the list until you find the one that fixes the problem.
  1. Delete all the files in your ‘etc’ folder
  2. Clear Chrome’s host cache
  3. Update your drivers
  4. Configure your DNS servers
  5. Renew and flush the DNS

Fix 1: Delete all the files in your ‘etc’ folder

This is a simple fix. Just go to C:\Windows\System32\drivers\etc and delete all the files there. Then try accessing the internet again with Chrome.
Delete all files in your etc folder

Fix 2: Clear Chrome’s host cache

If Chrome’s host cache is corrupt or too full, you may not be able to access any websites. This is a very common cause of the problem, and quite an easy one to fix:

1) Open Chrome and type chrome://net-internals/#dns in the address bar, press Enter on your keyboard, then click the Clear host cache button.
2) Check to see if the problem is resolved.

Fix 3: Update your drivers

Sometimes the server DNS error is caused by an outdated, incorrect or corrupt driver – or more than one – that’s blocking your internet access to certain sites. So you should ensure all your drivers are correct, updated and in good health:

Automatic driver update (recommended)

Driver Easy will automatically recognize your system and find the correct drivers for all your computer’s cards and components. You don’t need to know anything about your computer or its devices, and there’s no risk of installing the wrong driver or making a mistake when installing:
1) Download and install Driver Easy.
2) Run Driver Easy and click Scan Now. Driver Easy will scan your computer and detect any problem drivers.
3) Click the Update button next to each flagged device or Update All to automatically download and install the correct version of the drivers that are missing or out of date on your system. (‘Update All’ requires the Pro version – you’ll be prompted to upgrade when you click Update All – Pro comes with full support and a 30-day money back guarantee.)

Manual driver update (advanced users)

If you’d prefer not to update your drivers automatically as described above, you can do it manually. This is an advanced method, and you should attempt this only if you’re very comfortable working on computers. To update your drivers manually, for each device, visit the manufacturer’s website and searching for the most recent correct driver for your operating system. Note that for some drivers, you may need to try both the manufacturer of your PC and also the manufacturer of the component itself.

Fix 4: Change your DNS server settings

If your DNS server settings are configured incorrectly, you may not be able to access the internet. Follow steps below to set them correctly.

1) On your keyboard, press the Windows logo key  and R at the same time.
2) Type control panel in the empty box and click OK:
3) View by Small icons then click Network and Sharing Center:
Control panel network and sharing center

4) Click Change adapter settings:


5) Right-click on the connection icon (either Local Area Connection or Wireless Network Connection), then click Properties:


6) Click Internet Protocol Version 4 (TCP/IPv4) then click Properties:


7) In General tab, do one of the following, depending on whether ‘Obtain DNS server address automatically’ is already selected. Either:
a) If Obtain DNS server address automatically is NOT already selected, select it, then click OK:
b) If ‘Obtain DNS servers address automatically’ IS already selected, select Use the following DNS server address instead, then enter the following server address and click OK:

Preferred DNS server: 8.8.8.8
Alternate DNS server: 8.8.4.4
8) Check to see if the problem is resolved.

Fix 5: Renew and flush the DNS

Windows automatically stores the IP addresses of the websites you visit, so they open faster the next time you visit them. But if this cache becomes outdated or corrupt, it can stop you from accessing the internet altogether. To see if this is what’s causing your problem, simply renew and flush the DNS:

1) Press Windows+R on your keyboard.
2) Type cmd then press Ctrl+Shift+Enter to open an administrator Command Prompt. (Don’t just press Enter or click OK as that won’t open the command prompt in administrator mode.)

3) Type ipconfig /flushdns and press Enter on your keyboard:


4) Type ipconfig /renew and press Enter on your keyboard:


5) Type ipconfig /registerdns and press Enter on your keyboard:
6) Reboot your PC and see if the problem is resolved.
Hopefully one of these solutions will fix your network error. Please let us know if you have any questions or comments.
