BEFORE YOU BEGIN

The classroom network consists of Windows Server 2008 student server A and B a connected to via an internal local area network. NT2670Srv##A the domain controller for the contoso.com domain, is running Windows Server 2008. Throughout the labs in this manual, you will install, configure, maintain, and troubleshoot application roles, features, and services on the NT2670Srv##A.

To accommodate various types of classroom arrangements, each lab in this manual assumes that the student servers are in their baseline configuration, as described in Lab 1-2 “Preparing an Application Server.” If you have not done so already, complete the initial configuration tasks in Lab 1-2-1 before beginning this lab.

70-643 Lab 2-2 Answer Key 3

Exercise 2-2-1 Installing the Web Server (IIS) RoleOverview In this exercise, you install IIS7 by adding the Web Server (IIS) role to

the computer.

Completion time 5 minutes

Question 1

Why is the Windows Process Activation Services needed to run the Web Server (IIS) role?

WPAS now handles incoming requests instead of the W3SVC service. This enables IIS7 to handle incoming requests that are based on protocols other than HTTP.


Exercise 2-2-2 Configuring Web Server PropertiesOverview Using the default Web site that Windows Server 2008 creates during the

role installation, experiment with the various IIS7 site display options.


Question 2

What conclusion can you draw from this result?

The IIS7 splash page must have been named iisstart.htm.


8. Press Ctrl+Prt Scr to take a screen shot of the Internet Explorer window showing the result of your page refresh. Press Ctrl+V to paste the image on the page provided in the lab2_2_worksheet file.


Question 3

What do you predict will happen when you refresh the Internet Explorer page again? Why?

The IIS7 splash page will reappear because Default.htm is one of the files remaining in the Default Document list.

Question 4

What is the result this time? Why is the result different?

The IIS7 splash page appears because Deafult.htm is listed in the Default Document list.

Question 5

What is the result this time? Why is the result different?

The IIS7 splash page does not appear because iisstart.htm is still not listed in the Default Document list. Instead, a page containing a directory listing appears because you enabled directory browsing.



Question How is this error message page different from the previous


6

one?

This error page is simpler and provides only the most basic information about the error.



Exercise 2-2-3 Preparing Web Site ContentOverview Before you can create new Web sites on your IIS7 server, you must have

content to publish on them.


Question 7

Why is it necessary to change the Save As Type value to All Files?

When IIS retrieves the content files from the Physical Path folder to publish them on the Website, it uses its own account, which does not have permission to access that folder. The Connect As dialog box provides IIS with the credentials it needs to access the content files, even when you are not logged on to the server.


16. Press Ctrl+Prt Scr to take a screen shot of the DNS Manager console showing the two CNAME records you created. Pess Ctrl+V to paste the image on the page provided in the lab2_2_worksheet file.


Exercise 2-2-4 Creating Web SitesOverview To test IIS7’s ability to support multiple Web sites simultaneously,

create two new sites, and configure them to respond to different URLs.



8. Press Ctrl+Prt Scr to take a screen shot of the Internet Information Services (IIS) Manager window showing the two Web sites you created. Press Ctrl+V to paste the image on the page provided in the lab2_2_worksheet file.

Question What happens?


8The Web page you created containing the www##.contoso.com URL appears.


10. Press Ctrl+Prt Scr to take a screen shot of the Internet Explorer window. Press Ctrl+V to paste the image on the page provided in the lab2_2_worksheet file.


Question 9

What happens now?

The Web page you created containing the sales##.contoso.com URL appears.

Question 10

How is IIS7 able to distinguish between the two URLs when the www## and sales## names resolve to the same IP address?

Web browsers send their HTTP request messages to the server’s IP address, and the message header contains the URL you keyed in the browser.

Question 11

Which Web page appears when you key the URL http://NT2670Srv##A.contoso##.com? Why?

The IIS7 splash page from the original default Website appears because the default site has no host name defined in its binding. The incoming request has server## as its host name, which IIS7 does not recognize, so it forwards the request to the default site.

Question 12

Which Web page appears when you key a URL containing the server’s IP address instead of a name? Why?

The IIS7 splash page from the original default Website appears because the default site has no IP address defined in its binding. The incoming request has the server’s IP address as its host name, which IIS7 does not recognize, so it forwards the request to the default site.


Exercise 2-2-5 Creating Virtual DirectoriesOverview In this exercise, use virtual directories to publish content found at a

different location as part of an existing Web site.


Question 13

Why is the public folder you created accessible through the www## Web site?

The Public folder you created is subordinate to the root folder for the www## Website. IIS7 automatically publishes all folders subordinate to a Website’s root folder.

Question 14

What are the results of the authentication and authorization tests? Explain the results.

The authentication test passes, and the authorization test fails. The authorization fails because the IIS7 account does not have access to the C:\Users\Student##\Links folder.

Question 15

What are the results now?

The authentication and authorization tests complete successfully.

Question 16

What URL must you use in Internet Explorer to access the virtual directory you just created?

Use http://www##.contoso.com/Links.

Question What is the result?


17The content of the Links folder appears.

Question 18

Why does the Links folder not appear?

You enabled Directory Browsing for www## at the site level, and sales## is a different site.


22. Press Ctrl+Prt Scr to take a screen shot of the Internet Information Services (IIS) Manager window. Press Ctrl+V to paste the image on the page provided in the lab2_2_worksheet file.


LAB REVIEW: QUESTIONS


1. In Exercise 2-2-2, you saw the two different types of error pages that IIS7 can generate. By default, the Web server displays detailed error pages in response to local requests and the simple error pages in response to remote requests. What is the main reason for providing less error information to remote users?

Detailed error message pages include information about the Web server and the computer running it that an unscrupulous individual might be able to use to compromise the Web server and its network.

2. In Exercise 2-2-3, you created two CNAME resource records in your domain using the DNS Manager console. Why was it necessary to create these records?

It was necessary to create resource records registering two different names for the Web server so that IIS could differentiate between the incoming requests intended for the two Websites you created.

3. In Exercise 2-2-3, why did you create CNAME resource records instead of standard Host (A) records in the DNS?

A CNAME resource record is an alias that equates one fully qualified domain name with another, while a Host record equates an FQDN with an IP address. By creating CNAME records and equating the alternative names with the server’s original FQDN (server##.contoso.com), the aliases remain valid, even if the computer’s IP address changes.

4. In Exercise 2-2-4, you configure your two new Web sites to use host name bindings. Why is this binding method preferable to using a different port number for each site?

Port number bindings require users to specify the alternative port number in their URLs.


LAB CHALLENGE: CREATING PORT NUMBER BINDINGS


Your supervisor wants you to experiment with the different site binding strategies supported by IIS7. To complete this challenge, create a Web site called testsite##, containing the same type of dummy content you used earlier in this lab. The Web site must be accessible using any of the following URLs, where ## is replaced with the number assigned to your computer:

http://server##.contoso##.com:1024

http://testsite##.contoso##.com

http://testsite##.contoso##.com:1025

http://testsite##.contoso##.com

http://testsite##.contoso##.com:1026

Create a list of the tasks you must perform to achieve your goal, and take five separate screen shots of the Internet Explorer window, displaying each of the five URLs successfully connected to the site. Paste the images in the lab2_2_worksheet file.

1. Create a folder called testsite## in your Documents folder and a Default.htm file containing dummy content.

2. Create a new site called testsite## using the testsite## folder you created as the root.

3. Use the Connect As dialog box to supply the credentials that IIS7 will need to access the root folder.

4. For the first binding, use the Port value 1024, and leave the Host Name text box blank.

5. Open the Site Bindings dialog box, and create four additional bindings for the site.

6. For the second binding, use the Host Name value testsite##.contoso.com, and leave the default Port value of 80.

7. For the third binding, use the Host Name value testsite##.contoso.com, and change the Port value to 1025.

8. For the fourth binding, use the Host Name value testsite##.contoso##.com, and leave the default Port value of 80.


9. For the fifth binding, use the Host Name value testsite##.contoso.com, and change the Port value to 1026.

10. Open the DNS Manager console and, in the contoso.com zone, create a CNAME record with the alias name testsite## and the target host NT2760Srv##.contoso##.com.

11. Create a new DNS zone called contoso##.com, and create a CNAME record in it with the alias name testsite## and the target host NT2760Srv##.contoso##.com.
